RE: Issue with TLF applyFormat in Flex 4.10

[Jason Taylor]

again, can anyone point me in the right direction here?  We can't apply any 
formatting to a range of textflow in Flex 4.10.  This issue is specific to the 
4.10 SDK.  This sample produces the error. Stackoverflow question here: 
http://stackoverflow.com/questions/19168415/applying-formatting-to-a-character-range-in-textflows-in-flex-4-10-sdk

Our app relies on highlighting text, so this is a pretty major issue for us at 
the momment.

Hi guys, please point me to the right place if this is the wrong.  I have 
encountered what appears to be an error in TLF present in the 4.10 SDK (checked 
multiple flash player target versions) in regard to EditManager.applyFormat

in the selection state I am specifying a small character range, but the format 
gets applied well beyond that range.  Attached are images from the exact same 
code (provided below) with drastically different results.  

Thank you for any assistance & advise.
