Yes, we do want to fix this bug (in Company).

But I meant something different: if the display engine worked 
consistently between step 6 and step 9, the bug would've been easier to 
reproduce, and might have already been fixed at this point.

Maybe I would've already noticed it myself (instead of waiting for a 
user to report it), and it could have influenced the choice of the popup 
rendering strategy.
