Global menu non working in the flatpak version of Waterfox

[neffscape]

One of Waterfox' best features is Global menu support (in the KDE Plasma version). Please try to solve this issue :). Thank you for your work!

I'll look into this, should be simple but it may just be a Flatpak limitation. I don't personally use KDE so it's great to have input on this from someone who does!
