Symo:

This control seems to have some issues in Firefox 25.0:

 

1. Hitting backspace seems to remove HTML chars rather than 'design mode' chars. (producing <br> at the end of the document for instance.

 

2. It seems to go into a mode where all editing is done in one character spot.

 

 

Can you reproduce this issue in this example?
