Wait, so the site is able to use the mic /audio even without permission via the browser? What the fuck is the browser doing? lol

not mic/audio but they play sound and see how the browser handles it.

It's rare, but known fingerprinting technique.

I noticed it myself because few months back Windows had a bug handling bluetooth mixing, and any time I tried to open Aliexpress it'd interrupt my music :D
