Currently, colors with an alpha channel defined with the 'rgba' function are not respected, for example, the following:
<span style="background-color: rgba(0, 0, 0, 0.5);">Some text</span>
It is imported as black color; semi-transparent colors are exported without the alpha channel.

The control exposes the OpenedFileName property which will be set when a document is opened. When we try to open a new document, but instead click the Cancel of the OpenFileDialog and close the dialog, this property will be reset. However, the document stays the same. In this case, this property should not be reset.

When changing the theme through ThemeResolutionService.ApplicationThemeName all the application gets changed. Except the ForeColor of the RadRichTextEditor does not get change. Hence the box displays black text on a dark background. Quite unreadable.
Assigning the theme directly in the designer makes everything renders ok.
Sample application attached.
Regrads,
Matthias
