[Bug 1581578] [NEW] The input field is displaying only upper half when Firefox isn't in full screen

[Yimga Yimga Salathiel Genèse]

Public bug reported:

As I' writing my plug-in, I use console to debug & see how my code is
working. I may write some code the console to make sure of how a
function is working.

But two days ago, I wonder I cannot see well the content of my command
in the developer console. Just the upper half is visible. The lower half
being hidden due to ... end of window boundary.

Just before I submitted this bug, I switched to full screen mode: what
my surprise to see my console fully displayed. It even went up about
10px... and as I'm writing, I see the URL bar & add-ons of the same line
displayed only lower half because of top window boundary.

Thanks in advance.
