Yep, that’s got it, thanks for your time, Ed!
It looks like I can remove the size resetting lines above from my own code, I will let you know if there’s anything else associated with it, but it all seems good in the one minute test I did just now. 
edit BTW does that fix need a ‘#if JUCE_WINDOWS’ around it?
Thanks, worked for me too.
No, only this one, I still need the hack when component hierarchy is changed.
Just figured out the hierarchy bug happens only on macOS, in case someone cares.
