Web API AudioTrack property

Zygarde Exe

Hi, I’m trying to use the audioTracks API from the Web API. I found out that I need to enable a specific flag in Firefox, but it doesn’t seem to be working as expected. Even though my video has multiple audio tracks, it only shows one audio track and doesn’t list their properties correctly. But In Chrome, Edge and Safari it is working as expected. Here I am attaching the screenshots of both Firefox and Chrome for comparison. The Blank drop down is from FireFox.

Hi, I think it's better to report it on https://bugzilla.mozilla.org. Thanks!
