[Fix] Zoom now always retained after minimize, restore, etc.

Resubmitted after technical difficulties. Accidentally ruined the branch I'd submitted previously.

On my machine, this resolves the problems described in #2156

On recent Heroic versions, whether the problem is present at all seems to vary by Linux distro. I had the problem on Ubuntu 24.04 LTS.

On machines that don't have the issue my changes should just add redundancy. I only have my machine to test with but my symptoms were identical to what others were describing, so hopefully this helps everyone affected.
