These are the same problems that I've seen in the bug reports, and when 
testing posframe-company: some platforms complained about focus issues 
(which, to be fair to the author, he worked on resolving), and with 
general responsiveness somewhat worse than the overlay-based popup.

It would really help if someone with experience in GUI programming on 
several platforms did some work on the feature. Or created a more 
focused popup primitive which would use native solutions on each 
platform (while supporting all the same text formatting, though).
