Wrong zoom shortcut behaviour in Firefox browser, Figma or Figjam

Hello,
I’m Working on Firefox 118.0.2 on IOS

Zoom in (⌘-) works correctly, it zooms only content.
Zoom in (⌘+) zooms content but also the UI.
Zoom to 100% (⌘0) doesnt work, to reset anything, I have to use the menu, then it works.

The only topics I found about this are unfortunately already closed. Also, none of them deal with the browser version.

I can’t put the question here in the forum as a bug, the only choice I have here is the category “plugin and widget bugs” but not the Figma or FigJam browser version. So for now I’ll ask the community.
Since I am new here in the forum, maybe someone can help me where the right category is?

Best regards
Nadine
