Oh I did not mean to propose that as a solution on the Emacs side, sorry 
if that wasn't clear. It was meant as a temporary workaround for 
affected users before an official solution lands.

I did not know `resize-mini-frames` is already allowed to be a function, 
I don't use that feature at all so I'm a bit clueless about possible 
settings. It doesn't look like `window--resize-mini-frame` is called 
anywhere? Is that function meant for users?

Sounds like a good approach to me. Thanks for thinking it through!
