Didn't see this little bug until i started using 0.9.99.

 

I am entering text into the Item field in the wysiwyg grid cell editor.  When I reach the end of the line and the text wraps to a new line, the editor appears to deactivate momentarily.  The background color of the cell being edited changes to the color of a cell that is not in edit mode.  But then the wysiwyg editor seems to reactivate automatically on the new line, and I can resume editing.  The "inactive" background color goes away.  It's a bit disconcerting visually, and there may be some delay involved in the apparent deactivation-reactivation, but I haven't really tested that.
