Somewhere around version 131 or 132, Firefox has started being more paranoid about media device fingerprinting, and will not even give you the IDs of available devices until you've requested a media stream. Instead you only get a single audio input and video input each with the empty string as their device ID, representing the system's default device. We can recognize this case and avoid resetting the device selection.
Closes #2770
