Symptom is the _html5AudioPool fills with unbounded number of elements if unable to unlock (seen on MacOS Safari).
When not allowed to unlock audio, we're seeing
unlockbeing called on every touch event indefinitely, leaking Audio elements, causing a big slowdown in our app after a few minutes. This happens on Mac OS Safari when audio is not allowed to be unlocked (microphone was in use by another tab, I think).It appears to also be thrashing AudioBufferSources and related state as it keeps making new sources and trying to play them and binding new onended callbacks, but I don't see an easy way around that.
My fork has diverged quite a bit, but I think this PR captures the change into the right place for the mainline.
