Break stack undo in RichEditableText when I make one or more operations ApplyFormatOperation sequentially

I don't doubt its a bug.  Interpreting the instructions and creating an actual bug is a bit of work.  It'd be a lot simpler if you could fill in an AS3 example program with the actual details so that running it just reproed the bug.  It will get attention much faster that way.

Follows is an AS3 template.

That would be much appreciated.
