STR_1:
0.(new versions) Open about:config, set "browser.tabs.delayHidingAudioPlayingIconMS" to 0
1. Open https://www.youtube.com/watch?v=mD3v1B_aXw0
2. Open http://example.org in a new selected tab
3. Wait more than 10 seconds
4. Click on the tab from Step 1

AR:  Sound indicator in the tab from Step 1 briefly disappears and appears again
ER:  Sound indicator should be constantly displayed (assuming you performed STR_1 in less than 141s)

Jared - this doesn't look like a platform issue. Can you shed some light on this?

There is discussion about this in bug 1337492. It appears related to how SVG graphics are loaded and painted.
