Steps to reproduce:
1. Write a couple of words: one two three
2. Select the second word two without the spaces around it and delete it
3. You'll see a single space between one and three in Design mode, while they are actually two in HTML mode.

When a partially copied table is pasted into the Editor in Chrome, it is pasted wrapped in the folloing div, making it not visible:

<div class="telerik_paste_container" style="border-width: 0px; position: absolute; overflow: hidden; margin: 0px; padding: 0px; left: 3px; top: 215px; width: 1px; height: 1px;">
...
</div>


Steps to reproduce:
1. Open http://demos.telerik.com/aspnet-ajax/editor/examples/overview/defaultcs.aspx
2. Clear the contents of the editor
3. Insert a table (any configuration of rows and columns) 
4. Go to a new line
5. Type a word on the new line
6. Select the word and a partial amount of the inserted table
7. Copy
8. Paste
9. Navigate to the HTML browser of the editor
10. Observe the "telerik_paste_container" still wrapping the pasted content

Workaround:
<telerik:RadEditor ID="RadEditor1" runat="server">
</telerik:RadEditor>

<script type="text/javascript">
	var editorPrototype = Telerik.Web.UI.RadEditor.prototype;
	var onAfterPaste = editorPrototype._onAfterPaste;
	editorPrototype._onAfterPaste = function (range, tmpPasteContainer) {
		try {
			onAfterPaste.call(this, range, tmpPasteContainer);
		} catch (e) { }
		$telerik.$(this.get_contentArea()).find(".telerik_paste_container").remove();
	};
</script>

The video object inserted in Design mode still present after switching to HTML view. he issue is reproducible in IE11 and IE10.

Steps to reproduce:
1. Navigate to http://demos.telerik.com/aspnet-ajax/editor/examples/clientsideevents/defaultcs.aspx using Internet Explorer 11(11.0.9600.17105 - i assume that if one has ie11 it is this version)
2. Click the Media Manager in the toolbar.
3. Navigate to the folder "PublicRelations" and select the movie "RadNavigation.avi" or upload and select another file.
4. Click insert.
5. Switch to the HTML view in the bottom

Result: The movie is still present even though the view has been changed to HTML. I've noticed that this only occurs when the movie is set to autoplay and its play. If I wait till the movie has stopped and try and switch from Design to HTML it seems to work.

Hi Telerik Team,

There is one recent problem we faced when copy paste of email address doesn't get open in outlook as HREF property is not set in Edge Browser. The functionality working fine in IE 11.

We are using version telerik version ASP.NET AJAX Q2 2016.

Attached is the screenshot of html. 

If the content of the editor contains an inline style which starts with - as -webkit-text-... like in:

<h1 style="-webkit-text-stroke-width: 0px;">My Title</h1>

A server error is thrown:

Server Error in '/' Application.
Name cannot begin with the '-' character, hexadecimal value 0x2D.

Current workaround is provided in the archive below. It consists of a function override that prevents the attribute loss. Below the workaround is the repro sample that invokes the validation.

When the Editor is configured to occupy size in percentages and the user switches from default to full screen mode and vice versa, the content area of the control gets broken. The problem is reproducible in all browsers.

As a temporary workaround you can attach a handler to the Editor's ClientCommandExecuted event and repaint the Editor in case the current command is ToggleScreenMode:

        <div style="width: 700px; height: 500px">
            <telerik:RadEditor ID="RadEditor1" runat="server" Width="100%" Height="100%" OnClientCommandExecuted="OnClientCommandExecuted">
                <Content>
                <p>dsadasdasdad dasdasdd das dasdasdasd <br />
                    dsadasdasdad dasdasdd das dasdasdasd <br />
                    dsadasdasdad dasdasdd das dasdasdasd <br />
                    dsadasdasdad dasdasdd das dasdasdasd <br />
                    dsadasdasdad dasdasdd das dasdasdasd <br />
                </p>
                </Content>
            </telerik:RadEditor>
        </div>
        <script>
            function OnClientCommandExecuted(editor, args) {
                if (args.get_commandName() == "ToggleScreenMode") {
                    editor.repaint();
                }
            }
        </script>

A proper workaround for this problem is applying this CSS rule:

div.RadEditor .RadRibbonBar .rrbButton img.rrbButtonImage {
    top:-7px;
}

An additional <br /> element is inserted in the editor when the following steps are executed:

1. Make sure ConvertToXhtml filter is turned on.
2. Switch the editor in HTML mode
3. Set the HTML bellow:
<div class="line1">first line of text</div>
<div class="line2">lastlineoftext</div>

4. Switch back to Design mode.
5. View the HTML using Module Manager - Real Time HTML Viewer
Expected HTML:
<div class="line1">first line of text</div>
<div class="line2">lastlineoftext</div>

 Actual HTML:
<div class="line1">first line of text</div>
<div class="line2">lastlineoftext</div><br>

 

Currently the <br> element cannot be removed from the HTML code of the content. This element exists by design and it is inserted in the editable iframe by the browser. The <br> element is used as a non-breaking line, which means that the following row can be selected and characters can be typed in it. If such element does not exist, the users will be unable to select the first row of the content area and start typing. 

The ConvertToXhtml filter actually removes this element when switched to HTML mode and retrieves it back as a last child of the <body> element, due to the above mentioned reasons. 

If you have issues with the retrieved content via the get_html() method, note that stripped content is returned when the method is used with an argument value "true".

editor.get_html(true) - returns the HTML content, stripped by the set filters.

editor.get_html(false) or editor.get_html() - returns the raw HTML content as it is currently. The same as the editor.get_contentArea().innerHTML property. 
 
 WORKAROUND:
Disable ConvertToXhtml filter in codebehind:
RadEditor1.DisableFilter(EditorFilters.ConvertToXhtml);

			<telerik:RadEditor ID="RadEditor1" runat="server">
				<Content>
				select and delete some of the "th" content, the entire cell element will be deleted instead of its content
					<table>

						<thead>
							<tr>
								<th>th1</th>
								<th>th2</th>
								<th>th3</th>
							</tr>
						</thead>

						<tr>
							<td>1</td>
							<td>2</td>
							<td>3</td>
						</tr>

					</table>
				</Content>
			</telerik:RadEditor>
			<script>
				//workaraound

				Telerik.Web.UI.Editor.DeleteSelectionCommand.prototype.deleteNodeContent = function (node) {
					var utils = Telerik.Web.UI.Editor.Utils;
					if (utils.isTag(node, "td") || utils.isTag(node, "th")) {
						utils.removeChildren(node);
						node.innerHTML = NBSP;
					} else {
						remove(node);
					}
				}
				
				function remove(node) {
					node.parentNode.removeChild(node);
				}
			</script>

Finding is stuck to the last possible occurrence and cannot proceed to the next match.

The changes applied to a newly uploaded image through the ImageEditor are not taken into account when inserting the image in RadEditor. The issue is reproducible in all browsers.

When copying text using the keyboard, the content is not copied. Instead is is marked as deleted and the selection is moved to the end of the selection.

The formatting of nested lists is lost when pasting from Word in IE10. The issue is reproducible also in IE8 and I9.

Currently the " entity is converted to a single quote under Chrome or Firefox, when ConvertToXhtml filter is enabled and the entity is placed in the value of an HTML attribute, for example href.

For example:
If this is the HTML in the editor
<p><span style="font-size: 11pt; font-family: 'Times New Roman';">Test Test Test<br /></p>
selecting only a part of the element and clicking Strip Formatting will not remove formatting

Another example:
When in a list, individual items cannot be cleared of formatting, e.g.:
<ul>
<li><strong>bold</strong></li>
<li><span style="text-decoration: underline;">underline</span></li>
<li><em>italics</em></li>
<li><strong><em><span style="text-decoration: underline;">bold underline italics</span></em></strong></li>
<li><strong><em><span style="text-decoration: underline;">Underline, Bold, Italics</span></em></strong></li>
<li><strong><em><span style="text-decoration: underline;">Italics, Bold Underline</span></em></strong></li>
</ul>
selecting (a part of) a li element and clicking Strip Formatting will not remove the formatting.
