Hello,

There seems to be an issue with the "Strip Span Elements" tool when pasting content into the editor in Design mode.

I have made a screencast demonstrating the issue available here: https://www.screencast.com/t/1OZ1huYPde8H

Reproduce:

Open a RadEditor demo that has the "Strip Span Elements" option like the Overview(https://demos.telerik.com/aspnet-ajax/editor/examples/overview/defaultcs.aspx) or the Right Editor in this demo(https://demos.telerik.com/aspnet-ajax/editor/examples/cleaningwordformatting/defaultcs.aspx).

In a word document create text that when pasted into the editor has spans, for example changing the background color or the text color. 

Copy the text from the document into the "Design" mode of the editor.
Select the text you would like to strip span's from (I used all of the text in the screencast example).

Use the "Strip Span Elements" button.

Switch the editor mode to HTML(The spans are not stripped).

Switch back to design mode.

Select the text you would like to remove spans from again.

Use the "Strip Span Elements" button. The spans are now stripped.
 


Expected result: Strip Span Elements option removes <span> tags from html directly after pasting into design mode.

Actual result: Strip Span Elements option does not remove <span> tags on pasted text in the design mode until you navigate to HTML mode then back to design mode.
 
Any help and suggestions are appreciated.

Thanks,

Calvin Williams
