Strange top bar when hiding tabs

Describe the bug

Hello!

I'm placing my tabs on the side bar. I've added this to my userChrome.css to hide the top bar as well as the sidebar header:

#TabsToolbar {
    display: none !important;
}

#sidebar-header {
    display: none !important;
}

My issue is that it gives something strange when I use Firefox in full screen :

The url bar is clipped in a strange way. This does not happen when Firefox is windowed :

It didn't happen before I added Firefox-UI-Fix Lepton even though I already used the above css so it must come from a conflict between some Lepton rule ant one of these (most likely the TabsToolbar one).

Expected behavior

I'd like to fix the clipping when Firefox is in full screen
