BUG: appmenu-plugin not taking up full width

[hart-rob]

Rhino Linux Version:
Rhino Linux 2023.4

Platform:
x86_64 Intel i3-5005U (4) @ 1.900GHz

Describe the bug
The global menu (appmenu) plugin is active, but only occupies an icon-width of the panel. It's not possible to use as most of the menu is not visible.

To Reproduce
Steps to reproduce the behavior:
It's there all the time, even if I remove appmenu-plugin from the panel and re-insert it. I created a new user and logged in as them and it has the same problem.

Expected behavior
The global menu (appmenu-plugin) should take up all available space in the panel.
