Tab label height and its margins

Hello,

Forgive me if this is not the right place to ask this.

I'm on Firefox beta 133.

I'm trying to reduce the height of tab label, together with "autohide_bookmarks_and_main_toolbars.css"

I use these lines: :root { --tab-min-height: 24px !important; }
:root #tabbrowser-tabs { --tab-min-height: 24px !important; }

And changed this with -40px, to avoid gap under the tab label container, when main toolbar and bookmars are auto-hidden:

:root[uidensity="compact"] #navigator-toolbox{ --uc-navbar-height: -40px;

But it just doesn't feel right. After the changes made, now the urlbar height is increased:

Sometimes when I launch or reboot the browser, the urlbar height is correct but toolbar overlaps tab label:

Anyone can help please? Thank you
