1777571 - Under Wayland, screen sharing prompt should not show a dropdown widget since there is only a single choice ("Use operating system settings")

Status: NEW

(Core :: WebRTC, defect)

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:101.0) Gecko/20100101 Firefox/101.0

Steps to reproduce:

Under a GNOME Wayland session (running on Fedora 35 for example), go to https://meet.jit.si, enter a random conferencing room, and click the button to share your screen.

Actual results:

As you can see in the attached screenshot, it shows

Window or screen:
  [ Use operating system settings    ⏷ ]

However, that dropdown widget is not interactive in practice, because "Use operating system settings" is the only option.

Expected results:

Do not show that label and combobox when the only choice is to let the operating sytsem prompt the user for what they want to share; it's out of Firefox's control.

[BugBot [:suhaib / :marco]]

The Bugbug bot thinks this bug should belong to the 'Core::Widget: Gtk' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Setting this to NEW as I managed to replicate on Ubuntu 22.04 on latest version Firefox 102.0.1.
Also, moving this to Core: WebRTC. If this is not the right component, please move it to a more appropriate one.

It happens on MacOs too since last month.
MacOS Sequoia 15.2, Firefox 134.0.1 (aarch64).

I already tried to:

1. Restart computer
2. Restart firefox in safe mode
3. Reset firefox permissions on system settings and via terminal
