Incorrect overflowing on Android

[corrideat]

Problem

On some Android and browser combinations, the settings menu overflows beyond the physical screen size, while it should not.

See these screenshots on a Samsung S21 Ultra using Samsung Internet (where the issue happens) and Chrome (which works correctly)

Solution

Identify the issue and fix it. This issue is 'surprising' because SI and Chrome both use the same engine, maybe with some small modifications. My guess is that the app uses some 'new' CSS that isn't yet supported by SI.
