This should fix some of the audio stuttering issues when the HTML5 export is compiled with threads support. The API should be ported to AudioWorklet to (hopefully) be perfect. That though, cannot be backported to 3.2 due to extra restriction of AudioWorklet (which only runs in SecureContext, and needs a polyfill for Safari).
