Hi
If I goto http://www.richtexteditor.com/demo/ then double click on the first image, the properties dialog box appears. If I then click on tooltip and try to type only the first letter typed appears. If I do the same on long description the first letter appears here also but the rest goes into the html. Click again on long description and it works fine, so does the tooltip.
Can you recreate this.... IE 11 only?
Will it be fixed?
