Re: [jira] [Comment Edited] (FLEX-35078) Fatal when SelectionManager
tries to reapply selection onto changed textFlow
If anyone with TLF knowledge wants to take a look at this, it would be
quite helpful. Some of the investigation work is already done, and
someone who understands what _should_ happen can probably spot the
problem quickly. Thank you!

Hi Mihai,
I forgot about this. I’m not going to have time to look into this for at least a week or two.
Please email me a reminder to take a look in a couple of weeks…

>>>>>>> *Workaround*: call {{display.validateNow();}} before {{display.setFocus();}}
>>>>>>> *Notes*:
>>>>>>> * couldn't reproduce the bug with only one line; we seem to need the text to wrap around the second line.
>>>>>>> * couldn't reproduce the bug if the span representing the bullet text wasn't set to an explicit font size (of any value).
>>>>>>> * could reproduce the bug with many random (non-empty) strings for the bullet text, including one space.
>>>>>>> * could reproduce the bug when I set the fontWeight instead of the fontSize on the bullet span. It seems that anything that will get the bullet placed into a separate span rather than merged with the span containing the main text will reproduce the bug.
