opening webm randomly opens only preview

[modrei]

when i click a webm (regardless of it being in catalog/thread) it has a good chance of opening the preview pic and i have to scroll back and forth to actually play it, progress bar loads and sound plays too, however the video is not playing

[obscenelyvague]

I've been encountering a similar bug with the app's built-in video player where even after a webm has fully finished buffering it fails to play it back. Except in my case the playback is fully halted, no audio and momentarily swiping to view a different webm (which may load without problems) and swiping back to the affected webm also doesn't help resume playback. The play button obviously also does nothing. It remains stuck in that limbo state unless you hit back and then view the webm again, in which case the video player is reinitialized and loads it just fine from cache. This isn't a new bug. I've had this happen for the longest time. Possibly since the beginning. I'm attaching logs in case they're helpful in any way.

The bug occured when trying to load the 1672954923725512.webm file in this instance. A possible reproducer might require:

1. A slow and unstable internet connection.
2. A relatively big webm (at least 4MB).
3. Not letting preceding webms in a thread fully load when swiping through webms in a thread.

2. A relatively big webm (at least 4MB).
3. Not letting preceding webms in a thread fully load when swiping through webms in a thread.

i have tested on both mobile data and fiber, its not due to speed, at least not from the users side

and yeah not letting preceding webm fully load will result in both webms playing audio over each other, but thats rather rare and preventable unlike the original issue
