I set a minimum height on a RadRichTextEditor control so its height would expand as the user typed more into the editor.  This caused different issues on both Android and iOS.

On Android: As the height attempts to expand, it gets caught in an infinite loop where the bottom of the height is shaking.  I believe this is because the call to  UpdateContentSize in OnSizeAllocated causes a re-render of the underlying webview, which causes it to keep resizing over and over.

On iOS: The editor height never expands, but I believe this might be a platform issue and not a telerik issue.

When copying formatted text from outside the control (Notes on iOS for example), and pasting it into the RichTextEditor using the context menu commands, the formatting is not applied.

In iOS if you are on a page with a rich text editor, then navigate to a new page, the editor gets unloaded.  When the user navigates back, the document is still unloaded and is no longer functional.  This is not a problem on Android.

Here is a stack trace of when that document gets unloaded:

Exception is thrown when resizing image from the Add/Edit toolbar.

When setting TextColor to the editor, the color does not change. 

The background color is not applied for the RichTextEditor control.
