Mobile: Firefox renders large black bar below menubar

[Asinin3]

Description

Firefox Mobile 153.0.3 renders the menu bar incorrectly taking up more space than it should:

Noting this is not an issue if you install qui as a PWA app through Firefox. Though Chrome renders the page correctly without PWA so it is a browser issue.

No other extensions were enabled when testing.
