Expected Behavior

Cannot use a video in webm and set the currenttime. Always go to the beginning of the video and does not assume the currenttime. if we use other video codec it works, only webm doesn't.

In this case the video should forward to 5s and on local file starts from the beginning, on internet file starts on 5s.

Problem In the last versions 29.x, 28.x and 27.x. It works on 26.x

This works on chrome versions tested on v75 and v114. Only fails on OBS.

Just need's to comment the local file and uncomment the internet file to test it.

Research direction

Start by running the supplied HTML example in OBS Studio 29.1.3, comparing the local WebM source with the internet source and checking whether currentTime reaches 5 seconds. Then trace the OBS browser plugin's media handling for local WebM files; done means the local file seeks to 5 seconds like the remote file without breaking the existing playback behavior.
