When RTB is placed in a ScrollViewer, typing causes invalid ScrollChanged events. They are caused by Caret's ScrollViewer, so using custom Caret and handling its ScrollChanged event should be a valid workaround.

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

When dragged from the toolbox, the wizard adds only <telerik:RadRichTextBox /> tag and does not generate XAML for the Ribbon UI. 

Workaround: On second attempt, the UI of the ribbon is generated as expected. Note: The generation is not working in Visual Studio 2017, even on the second attempt.

ArgumentOutOfRangeException is thrown when replacing all (Replace All button is clicked from the FindReplace dialog) occurrences of given text if the replace text is with smaller length than the searched text. 

For example if we have the following text written in the RadRichTextBox: "Some Text" and we want to replace all occurrences of "Some Tex" with "AA" (open find and replace dialog and click ReplaceAll button), the exception occurs

Workaround: Change the FindReplaceDialog with a custom one (see how in this SDK demo - ). In the new custom dialog, buttonReplaceAll_Click event handler, change the initialization of the 'startFindPosition' variable to be in the body of the while loop.

Words containing apostrophes are not recognized by the spell checker. Examples: 
- Some contracted forms , for example "they've"
- A lot of common French words, e.g. "Aujourd’hui", "qu’une", "n'est"

The issue could be observed for the single straight (') as well as for the smart (’) quote.

Add the all word parts to the dictionary, for example, to recognize "they've", both "they" and "ve" should be added to the dictionary.

Fix available in LIB Version 2017.3.1009.

If a document with default tab stops width 0 or imported or the value is set from the UI, measuring the document when it contains a tab causes an InvalidOperationException with message "MeasureOverride returned Nan".

Workaround: If the case is importing a document, change the default tab stop width to value which is not 0.

            if (document.DefaultTabWidth == 0)
                  // set this to large number if there are performance problems, e.g. 0.5. 
                  document.DefaultTabWidth = 0.01;

Steps to reproduce:
1. Load RadRichTextBox and add text in it.
2. Change default tab stops value from the Paragraph Properties Dialog -> Tabs Dialog to 0''
3. Add a tab to the paragraph.
Observed: InvalidOperationException with message "MeasureOverride returned NaN" is thrown.

Fix available in LIB Version 2017.3.1120.
