Currently, caret continues to blink even when typing or navigation is in progress (e.g. arrow key is pressed and held), which is inconvenient for the end users. Instead, the caret should stop blinking during these operations, similarly to industry standard apps like MS Word and OpenOffice.

Page field in header (or footer) of document created with mail merge is always evaluated to 1, instead of the number of the current page.

Possible workaround (attached):

- Do mail merges one by one
- Set header/footers anew to contain PAGE fields in each document
- Set FirstPageNumber = 1 to each first section in each document
- Merge with RadDocumentMerger

Improve measure and arrange of a document and its child document elements respectively - Span, Paragraph, Table, Section and etc. This will also improve the import time for large documents.

Characters like 🙋🏻 are not imported correctly and instead result in a series of question marks.

Fix available in LIB Version 2018.2.716.

When a preceding paragraph's size is increased, for example - font size is changed, or paragraph is split to two, then the selection of the consequent paragraphs is wrong. When the cursor is on the second line and attempt to select some part of it with the mouse is made, the first or the third line is selected.

Steps to reproduce: 
1. Create two paragraphs with multiple lines
2. Insert new paragraph after the first paragraph
3. Try to select second line of the third paragraph with the mouse

Observed result: First line is selected instead of second line being selected

Nested tables inherit alignment from its parent table or table cell when importing a document from HTML, but they shouldn't.
The paragraphs are also aligned incorrectly when their parent table has its align attribute set.

Copy/Paste Adobe Reader snapshots are displayed as blank images.

RadDocument instance leaks through StylesGallery when RadDocument is set multiple times in a sequence to RadRichTextBox - for example by setting RadRichTextBox.Document property multiple times.

Steps to reproduce:

- Start application containing RadRichTextBox with StylesGallery

- Execute this code on a button click: 

            this.radRichTextBox.Document = new RadDocument();
            this.radRichTextBox.Document = new RadDocument();


Observed: RadDocument leaks through the styles gallery.

RadDocument instances leak when editing a document containing a field and header/footer. The StyleRepository holds a reference to a style's document element.

Fix available in LIB Version 2017.3.1002.

The tab stop defining respective page number alignment correlates to the cell's width where the table of contents entry is positioned.

The pgMar element might be present but the margin information might be missing as shown below:
<w:pgMar w:header="720" w:footer="720" />
At the moment this overwrites the section margin information with 0. Instead the margins should remain as is.

Fix available in LIB Version 2018.2.820.

If RadRichTextBox contains a table and is placed in a window and then the window is resized horizontally, the table border are moved unexpectedly and change their place relative to the content of the documen. If the window is maximized and/or restored, some of the borders disappear.

Workaround: Execute the following code snippet in window's or RadRichTextBox' SizeChanged event handler:
if (this.MyRadRichTextBox.ActiveEditorPresenter != null)
{
    this.MyRadRichTextBox.ActiveEditorPresenter.RecreateUI();
}

NullReferenceException is thrown when measuring a document with floating image as the first element on a second page. The same problem can be observed during copy/paste of content, but with slightly different call stack: 

System.NullReferenceException: Object reference not set to an instance of an object.
   at Telerik.Windows.Documents.Layout.LayoutBox.get_ValidParent()
   at Telerik.Windows.Documents.DocumentPosition.GetCurrentParagraphBox()
   at Telerik.Windows.Controls.RichTextBoxUI.RadRichTextBoxRulerController.GetCurrentParagraphBox()
   at Telerik.Windows.Controls.RichTextBoxUI.RadRichTextBoxRulerController.AssociatedRichTextBox_LayoutUpdated(Object sender, EventArgs e)

Depending on the document structure, an InvalidOperationException with message "Removed LayoutBox should not be split. Such operation will result in invalid document structure." could be also thrown. A sample call stack is:

Telerik.Windows.Documents.Layout.LayoutBox.CreateNewFragment(Telerik.Windows.Documents.Layout.LayoutBox currentLineStartNode) 
Telerik.Windows.Documents.Layout.TableCellLayoutBox.MeasureOverrideInternal(Telerik.Windows.Documents.Model.SizeF availableSize) 
Telerik.Windows.Documents.Layout.TableCellLayoutBox.Telerik.Windows.Documents.Model.IBlockContainerLayoutBox.CallMeasureOverrideInternal(Telerik.Windows.Documents.Model.SizeF availableSize) 
Telerik.Windows.Documents.Layout.BlockContainerLayoutHelper.CheckAllFloatingBlocksAreIncluded(Telerik.Windows.Documents.Model.SizeF availableSize)

While clicking to position the caret at the beginning of a paragraph, the caret is jumping to the previous document position and returning back to the desired one.

When document with large images (the original image cannot fit on the page without resizing) are exported to PDF, the PDF document is visualized distorted by Adobe Reader.

The issue is regression, introduced in 2017 R1 SP1.

Workarounds: 
- Use images that can fit on the page.
- Zoom RadRichTextBox to scale which allows the large images to fit fully on the page.

The hyperlinks are not exported properly to DOCX, RTF and HTML format if the HTTP:// prefix is not added in the address when they were created.

Steps to reproduce:
1. Open RadRichTextBox and click on Insert tab -> Hyperlink
2. In address field type: www.telerik.com
3. Export the file to DOCX, RTF or HTML format
4. Open the exported file and click on the hyperlink
Observed result: The hyperlink is pointing to a local resource instead of opening the URL.

As a workaround, the regex used to match a partial hyperlink could be further extended. If this regex succeeds in matching a partial hyperlink the HTTP:// prefix will be automatically added to the partial hyperlink. Here is example of how the regex should be accessed:
(this.radRichTextBox.InsertHyperlinkDialog as RadInsertHyperlinkDialog).HyperlinkPattern

RadDocument.StreamFromUriResolving is not raised for the main document when InsertPictureField is included in header or footer.
