Maximized Firefox window leaks to other monitors

Hi, a long-standing problem is this: When Firefox is maximized in one monitor (the lowest one on my setup), the top of the Firefox window is leaked into the upper monitors by 10 pixels (if I see it correctly).

This only happens in the default setting of "Title bar" = unchecked (in the Customize Firefox settings). If "Title bar" is checked, then the window shrinks a little to fit the current monitor (just like a maximized window should be).

Is there a way to get Firefox to stay within the monitor limits when maximized even if Title bar is disabled?

Thunderbird does the same, but I guess they are using same components inside. No other programs have this problem.

Windows 10 21H2, using 175% or 100% display scaling, depending on the monitor (they are all 2560x1440 but the lower one is 14" (with 175% scaling) and the upper monitors are 27" (with 100% scaling)).

(The image upload does not seem to work, I'll send this anyway and try to add the screenshots in a reply.)

Image upload does not yet work, so no samples here.

I guess I was too concentrated in getting the images uploaded because I only now see the site suggesting other posts as well about this same problem, so others seem to suffer this as well, and there haven't been any answers here.
