A reference in DocumentFragment to RadDocument (CopySource property) can cause a memory after copy-paste between RadDocument.

Workaround:

public static bool ReleaseClipboardExReferences(
    RadDocument document)
{
    dynamic clipboardEx = new DynamicProxyObject(typeof(ClipboardEx));

    if (clipboardEx.documentClipboardData?.CopySource is DynamicProxyObject copySource
        && object.ReferenceEquals(copySource.Instance, document))
    {
        clipboardEx.documentClipboardData = null;
        return true;
    }

    if (clipboardEx.CopiedDocumentFragment?.Fragment?.CopySource is DynamicProxyObject fragmentCopySource
        && object.ReferenceEquals(fragmentCopySource.Instance, document))
    {
        clipboardEx.CopiedDocumentFragment = null;
        return true;
    }

    return false;
}

Use the attached project to reproduce:

- Click the first button so the image is changed

- Click the second button and examine the exported HTML

Expected: the Uri is exported

Actual: the Uri is not exported.

Workaround: 

To reproduce:

- Select several words by holding the control key. 

- Paste some text. 

Result: the first word is replaced, the other are deleted

Expected: the text should be pasted in all selected places

Workaround:

To reproduce:

- Hold the control key and double click a word

Actual: the entire paragraph is selected

Expected: the current word should be selected, the existing selection should be extended.

When the MEF catalog of RadRichTextBox is predefined, the PasteOptionsPopup is not automatically loaded and causes NullReferenceException in the presenter when the users press Ctrl or Esc.

Workaround: Add typeof(PasteOptionsPopup) to the catalog.

To reproduce:

- Add a multilevel list to a document and export it to HTML

- Import the document again the list is changed and the values are not correct.

The document styles are not respected because of wrongly imported custom style name after copy-paste from MS Word and exported to HTML.

Workaround: avoid using styles with braces in their name.
