Tails Installer allows buggy "Reinstall (delete all data)" on too small USB sticks

I have a (virtual) 4.3GB USB stick with an older Tails installed. I start Tails/Buster that has the newer Installer, it detects that my destination device has Tails installed already to the default option is “Upgrade”. So far, so good. But it also lets me choose “Reinstall (delete all data)”, which does not work: it is stuck at the partitioning step (iirc). I guess we should hide that button on too small USB sticks and only allow upgrading.

(I suspect that’s the fallout from an invisible merge conflict between kurono’s branch and mine, i.e. Git can’t notice things conflict because different code is modified on both branches, but the result of the merge does not work as it should.)
