Dynamic tab size on tabs with audio: Give a setting or about:config option to disable this

[jeffg01]

v136 introduced dynamically-expanding tab sizes on tabs with audio. This can be laggy though, as a page loads and the video/audio starts playing, causing misclicks. The tabs will also then shrink back down eventually once the audio's been idle for awhile, which can be visually distracting.

There's some kind of thing that can be done with userchrome.css, but this is a workaround that's not viable for most users.

@AgentvirtuelBy my reading of it, Bug ID 1945993 is something different. That issue looks like it concerns the tabs getting smaller than the specified minimum width. What I'm referring to is the fact that tabs will grow larger when audio starts playing in a tab. This was introduced in v136. Prior to v136, the mute icon appeared over the favicon, and the tab width remained the same size.

Yeah, this is driving me nuts. My tabs keeps on shifting left and right, especially when there are multiple tabs getting notifications. There *has* to be a configuration option for this. This also feels like an accessibility nightmare, though I can't personally confirm.
