how to prevent firefox detecting fullscreen change?

I've got full-screen-api.ignore-widgets = true, so that I can use the f11 key effectively as a "hide-the-toolbar" button. this works nicely since I can still use my window manager's fullscreen shortcut to actually go into fullscreen.

the problem is, whenever I do that, firefox detects the change and then shows/hides the toolbar again accordingly. just wondering if there's any way to stop firefox from detecting fullscreen changes?

I naively turned off exit-on windowOpen & windowRaise, but that had no effect.

any help is appreciated.
