Webm with alpha (v9) does not loop

Description of the issue:

A webm video with loop attribute does not loop on Brave

Steps to Reproduce (add as many as necessary): 1. 2. 3.

<video autoplay="" loop="" muted="" playsinline="" src="video.webm"></video>

Actual Result (gifs and screenshots are welcome!):

Plays one, then stops (or disappear, I don’t know because it ends on transparent frame anyway).

Expected result:

Loops normally.

Reproduces how often:


Brave Version(about:brave):


Additional Information:

Listening on videos ended event or trying to reset currentTime and calling play does not work either. As a workaround, I remove the video and recreate at an interval equal to video length.
