Firefox still playing audio after tab is closed

For a while firefox has been having issues where on youtube in particular when tabs are closed they will continue to play audio for a bit after they are closed. More recently I have closed tabs and the audio keeps on going indefinitely after the tab has been closed. This is on the latest firefox (151.0.4 64 bit) on windows 11.

This only seems to happen with youtube and in general youtube playback is buggy, slow, and lags the whole browser taking several seconds to switch tabs to or from a youtube tab or even close it.
