goratz commented on FLEX-34769:
-------------------------------
I have some troubles getting the numer of characters in the TLF if you have
images on the text sometimes they are counted but not always. Maybe that is the
problem with lines or maybe not.

> the second one is included in Apache Flex 4.9.1.
> I have a very large text, more or less 200 DIN-A4 pages in a Textflow. I
> scroll to the end of the document and I underline a word. This is my result
> underling a word in both versions.
> Flex SDK Version Time
> 4.9.1 21 ms (miliseconds). 0,02 Seconds
> 4.14 3.405 ms (miliseconds). 3,4 Seconds
