Playing HTML5 video detaches all Pulseaudio clients

Sometimes playing HTML5 video (YT, Twitch) hangs Firefox and additionally causes Pulse clients to detach from current service. Pulseeffects stops receiving any input and Spotify wouldn't play any song. Worth to note that pulse daemon seems to work just fine, as freshly launched Vivaldi can play videos while FF, Pulseeffects and Spotify are in an invalid state.

Restarting apps helps but bug is totally random (race condition perhaps?) and might show up 5 minutes or a couple reboots later. Conversely Spotify cannot reproduce described detaching.
pulseaudio -vvvvv doesn't produce any output at all.
Kernel 5.9.6-arch1-1
FF 82.0.2, installed plugins OpenH264 Video Codec provided by Cisco Systems, Inc. and Widevine Content Decryption Module provided by Google Inc.
pulseaudio 13.99.3

edit: happens in Vivaldi as well.

Re: Playing HTML5 video detaches all Pulseaudio clients

Sounds to me like pulse crashes and is restarted once you invoke a new client, what's your output of 

systemctl --user status pulseaudio
journalctl -b --user-unit pulseaudio

when this happens? Do you get a coredump?

*same stuff from systemctl logs*

So you were dead right, coredump had happened, not sure if it is need to be included here as it mostly repeats systemctl log.
Not sure what to do from this point, I guess gonna remove obsolete module and stuff

Re: Playing HTML5 video detaches all Pulseaudio clients

The obsolete modules shouldn't lead to such a crash. FWIW what are your sample specs, with a potentially crashing client open and playing, what's your output for 

pulseaudio --dump-conf
pacmd list-sinks
pacmd list-sink-inputs

it probably shouldn't crash regardless and would be worth to report but would be interesting what the general state is.
