iPadOS webkit seems to be working as expected; so this seems to be an osX Safari specific issue.

Made the following test via using StreamDestination, triggering sounds during recording.

If no sound is played following the initial playback;

1) Chrome reports a consistent Blob size of 238, each second.

2) Firefox reports a Blob size of 0 that spikes at 1047 in every 3-4 seconds.

3) iPad test is done within "Koder App". Assuming it uses webkit, it reports fluctuating Blob sizes of 0 - 604 - 1148 - 544 - 1208. Seems to be the least stable. Perhaps this report does not effect the recorded audio output, I was simply checking the signal flow for this test. Also during sound playback, block size is reported as 0 many times.
