After the update with AudioWorklet support there are glitches in the audio in all of the links below when playing on my Iphone XR:

The two links above has a polyfill and plays nicely if AudioWorklet is turned off.
The link below has no polyfill, relies only on AudioWorklet but has glitches even on my Macbook Air M1:

Plays without problems in Chrome/Firefox on the same Macbooc Air M1.

This might be an duplicate of https://bugs.webkit.org/show_bug.cgi?id=251091
However, I created a simple and minified test for this issue as well:
https://delude88.github.io/ios-audioworklet-sample-rate/
Each time any AudioWorklet is used on iOS it creates glitches, that still remain and affects the whole audio context - until the it is recreated.
