Unable to use language dialog with high zoom

[samth]

If I increase the zoom on my Linux laptop, and then open the Language dialog, and then choose "Other Languages", the dialog is too tall for the screen and I'm unable to get to the bottom at all.

Problem originally reported by Paul Snively on Slack, who uses high zoom normally for accessibility.

Thanks for opening this!

The situation is actually even weirder: on my Elementary OS 5.1 box (an Ubuntu 18.04 derivative), however the bounds for dialog frames are being computed seems to be completely wrong, and the text is bleeding outside the frame, up to some other bounds that seem to be invisible. Here's a screenshot:

This seems like it must be some rather deep error down in the bowels of the GUI framework, and probably very tricky to track down. Unfortunately (in that sense), DrRacket is the only software I've seen exhibit the issue.

Even without any zoom setting, the dialog doesn't fit my laptop screen.

There's a scrollbar, but as the dialog is not resizable the bottom portion of the dialog is inaccessible.

Note that when the dialog is first launched, it actually fits the screen. But selecting Other Languages lengthens the dialog making it taller than the screen. Disabling this automatic resize should fix this issue. (The scrollbar that appears when content grows is sufficient, no need to auto resize the dialog.)
