fix(): Disable offscreen check for bg and overlay when not needed

[asturur]

Motivation

closes #8887

the setting to make bg and overlay independent from zoom and panning are not respected by isOffscreen.
There isn't an easy way to solve this, and this one line fix is probably a way to block the bug for now.

We could have pulled the onscreen check outside of the render function but that could have unintended consequences on existing subclasses and also share the responsibility of offscreen check to more players ( canvas and group at least ).

Changes

The function to render backround or overlay will disable the offscreen check if needed and restore it later

I think you should fine tune tests and put in the description this regards only rendering

[asturur]

I see how the necessity of adding canvas to backgroundImage ( or overlay ) is unhandled.
This will need to be addressed somehow. Can't be left to the dev

Tests do catch regression
