radeditor adding <p>&nbsp;</p> . Actual HTML just have <p></p>

Also when we swtich beween edit, HTMl and preview . It add &NBSP;

Content appears double if there is a Style element inside it and the Spell Check is triggered.

Ability for the RadEditor's validator dialog to validate HTML 5 markup inside it's content

When hyperlinks are inserted into the content of RadEditor in preview mode there are additional attributes , which are retrieved by the get_html() method. 

If the MaxHtmlLength is set and the content is close to the limit on switching to preview mode breaks the normal behavior of the editor. The validator alerts that the length is exceeded, because of the additional attributes and the client is not able to open any other mode.

RadEditor uses a RadWindow for its dialogs so when the global rendering of RadCocntrols on the page is set to Lightweight the dialogs need to be consistent.
There could be implemented a property to control the RenderMode of the dialogs themselves.

Similar to the RadComboBox' OnClientFocus event - http://www.telerik.com/help/aspnet-ajax/combobox-onclientfocus.html

After upgrading to Q2 2003.2.611, I receive this error when an editor is being rendered, whether in a grid as a columntype, or standalone editor. If I remove the column, my popup comes up fine. I've even tried using the latest internal build to no avail.

Error: Unhandled exception at line 3407, column 1 in http://localhost:46674/Telerik.Web.UI.WebResource.axd?_TSM_HiddenField_=ctl00_rsmMaster_TSM&compress=1&_TSM_CombinedScripts_=;;Telerik.Web.UI,+Version=2013.2.709.45,+Culture=neutral,+PublicKeyToken=121fae78165ba3d4:en-US:69657036-201e-4b8d-ba50-faac1961b436:1569bb5f:63b115ed:874f8ea2:dc7e0bd:30f1f089:92fe8ea0:fa31b949:19620875:490a9d4e

0x800a01b6 - JavaScript runtime error: Object doesn't support property or method 'registerControlProperties'

Steps to reproduce:
1. Insert two lists
<ol>
    <li>test1</li>
</ol>
<ol>
    <li>test2</li>
</ol>
2. Copy the first list
3. Insert one more list item in the second list and paste the first list
Expected:
<ol>
    <li>test1</li>
</ol>
<ol>
    <li>test2</li>
    <li>test1</li>
</ol>
Actual:
<ol>
    <li>test1</li>
</ol>
<ol>
    <li>test2</li>
    <li>
    <ol>
        <li>test1</li>
    </ol>
    </li>
</ol>

When ContentAreaMode="Div" RadEditor's Content Area's width automatically re-sizes with the content. If width is applied to reContentArea div element, the problem is resolved.

Actual behavior: by placing a long word or pasting an image larger than the content area's dimensions, its width is automatically expanded. (see ActualBehavior.png)

Expected Behavior: the content area's width should remain unchanged despite word length and pasted image dimensions. (see ExpectedBehavior.png)

Radeditor when initially set as visible="false", the toolbar border images never renders when the control is later set to Visible="true".

The desired behavior cannot be achieved out of the box with the content provider from this KB article, because the paths to the images are passed to a generic handler.
The main reason it can't be achieved at the moment is that the latest moment of the page life-cycle of the FileBrowser.ascx dialog, when the user can set the FileExplorer's InitialPath is before the Page_Load event, but the path to the preselected in the Editor item is passed in the Page_Load event and the initial path is reset internally.

Steps to reproduce:

1. Go to http://demos.telerik.com/aspnet-ajax-beta/editor/examples/overview/defaultcs.aspx

2. Type some text

3. Format it as bold, italic and underline

4. Enter two new empty lines

5. Insert a table

It would be great to have RadEditor offer CMS type functionality similar to the RadEditor within Sitefinity. The Sitefinity editor allows you to drag and drop different layouts to the editor and then alter each area independently. 

Currently when pasting an ordered list from MS Word, the RadEditor’s lists converter does not take into account the list’s items numbering. 

The following list
 
5.	Li1
6.	Li2

will be converted to

1.	Li1
2.	Li2

Whe you're trying to add an image with "#" or "&" symbols in it's title - image displays as corrupted in image editor.

When dragging items from an outside source into a RadEditor, be it text, image, video, etc. The API used to perform drag & drop is lacking. For example, an overlay needs to be shown over the top of the iframe element for the editor, whereas I would like to perform the drop at a specified area where I drop - not where the cursor is located.
