Alex Harui commented on FLEX-34769:
-----------------------------------
In theory, Git merge should have preserved my flag. Did you run into conflicts?
AIUI, before you merged in the table work, TLF was working fine without needing
to reset to 0, but I don't know if we ever ran the current tests against any
pre-Table TLF. So that could imply that any RTEs in the current tests show
some reliance on reset to 0 which might shed light on what the issue was that
caused that workaround to go into the code.
Good luck.

> 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
