Firefox not minimizing properly in Secure Session

[MashedPotato247]

What Happened?

I often get stuck where I'm not able to minimize Firefox, I suspect that this bug is specific to Secure Session, but I'm not exactly sure, The system treats Firefox as minimized, but the window is exactly at the same place before it was hidden, if closed, it would leave a large black box on the desktop which is only resolved by logging out and logging in again. Please look into this bug.

Steps to Reproduce

This issue triggers randomly at any time.

Expected Behavior

The Firefox window should have minimized like any other window, but instead of that, it just loses focus and if closed, it leaves a huge black box on the desktop.

OS Version

8.x (Circe)

Session Type

Secure Session (Wayland)

Software Version

Latest release (I have run all updates)

The black box thing is probably the same as #2289
I have to add though that to my understanding it doesn't only happen when minimizing, but also when normally closing windows. And I experience it with Chrome (installed from .deb), too
