Issue 1 -

1. Use ff, go to an editor > select a text > click on the icon of (A/A) to show the drop down > select a heading level
2. Expected: The drop down closes
3. Actual : The drop down doesn't close.

This is not a issue in chrome, but is an issue with ie and ff

Issue 2:-

1. Add atleast 4 paragraphs to the content area
2. One by one change the size by selecting "heading 1" from the drop down, of first three paragraphs
3. Press ctrl + z 3 times
   Expected: - All changes are reverted
   Actual:- Only the last change is reverted
   Noticed this on chrome, ie, ff
