Firefox with tabs on the bottom breaks extension and tab pop up

Hyprland Version

v0.30.0

Bug or Regression?

Bug

Description

My firefox is modified with userChrome.css, allowing me to have tabs on the bottom as well as some extensions. One such extension is Tab Container. My firefox on swaywm allows Tab Container to open fully upwards in tiling mode, as well as tab collection. When in Hyperland however this feature breaks, only showing 1/4th of the open extension, this only happens in tiling, on floating this issue is fixed as the video demonstrates.

I feel it likely is to do with borders or space, the window not detecting the proper size and thus breaking down. I'm not sure however.

How to reproduce

1. Have Firefox;

2. Modify it with userChrome.css to have tabs on the bottom;

3. Install Tab Container extension;

3.5. Possibly have an ultrawide monitor?

4. Be in Tiling or PseudoTiling.

5. Tab Conatainer and Tab Collection Pop up don't open correctly.

Unfortunately no, but now I'm on qutebrowser. I kept this up because someone might end up with a similar issue.
