Focus events (GotFocus, LostFocus) are raised inconsistently for RadRichTextBox, due to the internal translation of the focus to the Caret.

Scenarios:

1. Clicking inside the control, when the focus is already inside the control, triggers LostFocus, GotFocus, LostFocus, GotFocus events.

2. Switching internal editors (headers/footers) raises GotFocus and LostFocus.

3. If the control is inherited and OnGotFocus/OnLostFocus are overriden, they are never called (despite OnGotFocus one time in the beginning

The behavior is problematic, as this events are useful for custom validation scenarios.

The exception is thrown by the SystemFontsManager internal class from Telerik.Windows.Documents.Core, so it can observed when using RadPdfViewer, RadRichTextBox, RadSpreadsheet.

The reason is not clear, posssible causes are:
- Corrupted fonts after upgrade from Windows XP
- Enabling of Block untrusted fonts feature (https://docs.microsoft.com/en-us/windows/threat-protection/block-untrusted-fonts-in-enterprise )

The call stack is as follows:

System.TypeInitializationException: The type initializer for 'Telerik.Windows.Documents.Core.Fonts.SystemFontsManager' threw an exception. ---> System.IO.FileNotFoundException: Unable to find the specified file.
   at MS.Internal.Text.TextInterface.Native.Util.ConvertHresultToException(Int32 hr)
   at MS.Internal.Text.TextInterface.FontList.get_Item(UInt32 A_0)

   at System.Windows.Media.Fonts.TypefaceCollection.<GetEnumerator>d__11.MoveNext()

Workaround: 

Manually delete all registry key values in Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts pointing to files outside of the Fonts folder.

Undoing changes to words wrapped in annotation ranges throw InvalidCastExceptions as AnnotationRangeStarts are casted to AnnotationRangeEnd.

Steps to reproduce:
1. Add a bookmark to a word
2. Add a bookmark to the following word in the document
3. Use the find dialog to highlight those two words
4. Bold the text
5. Press Ctrl+Z to undo
Observed: Repeated InvalidCastException dialogs

Fix available in LIB Version 2018.1.430.

After merging a document into another one (or pasting it), some of the content is duplicated. The issue is a regression in R3 2018.

The event is not fired when updating the IncludePictureField fields. It is also valid when the fields are in Header or Footer. The issue is a regression in R1 2019.

The UpdateAllFields() method of RadDocumentEditor can be invoked so the event can be fired and give you the possibility to update the images.

When calling a ChangeAllFieldsDisplayMode(FieldDisplayMode.Result) on a document containing a multiline document variable ("First Line\vSecond Line\vThird Line") leads to wrongly updated span box text.

The result is: "Third Line¬Third Line¬Third Line"

Closure reason:  issue fixed

Hi,

The issue is fixed and is live with today's LIB release (v.2015.1.0406)

Quickly adding/removing of tab stop from the document's ruler crashes the application.

Japanese users use distributed text alignment, which justifies all lines including the last one.

When paragraph is in list, the user can choose "Set Numbering Value" which will change the appropriate level Starting Index and will create a new list (or continue the previous one).

When TextOptions.TextFormattingMode="Display" is set on RadRichTextBox, incorrect Measuring causes TextBlocks to not visualize correctly.

"Based on style" combobox is not filled with all linked and paragraph styles in the following cases:
- "Modify style" dialog doesn't display the possible "based on" styles in the combobox when editing linked styles. 
- "Create new style from formatting" dialog doesn't display the possible "based on" styles in the combo box during creation of new linked style.

Steps to reproduce:

Variant 1:
- Click Home -> Styles -> Change Styles in the ribbon UI.
- Expand the the drop down of Heading 1 button and click 'Modify'
Expected: 'Style based on' combobox contains all paragraph and linked styles.
Actual: 'Style based on' combobox is empty.
-------------------
Variant 2:
- Click Home -> Styles -> Change Styles in the ribbon UI.
- Click 'New' button.
- Choose 'Style type:' Linked in the combobox.
Expected: 'Style based on' combobox contains all paragraph and linked styles.
Actual: 'Style based on' combobox is empty.

This results in prompt to save the changes when closing the file.

The fix is available in our latest LIB(v. 2014.3.1222).

When a field result fragment has multiple lines only the first and the last paragraph get the proper paragraph style properties.

When importing image with invalid ur/base64 encoded data the document won't be opened correctly and an exception will be thrown. Load default image instead of throwing exception and failing to open the document.

Import the type of the <ul> and <ol> tag, e.g. <ul type="disc"> or <ul type=circle>. Supported values are disc, circle, square.
