Description tim.spitzer 2022-08-18 06:41:02 PDT 
MediaStreamTrack.applyContraints does not resolve properly when applying multiple constraints in parallel to a MediaStreamTrack on Safari 16. 

1) Open the example at https://stackblitz.com/edit/js-gmbvkl?file=index.js
2) See console

Actual results: The promises returned from applyConstraints get stuck in pending state, except for the last one which is rejected.

Expected results: The promises returned should either be rejected or resolved based on the supported video resolution. The browser should enqueue and process the resolution changes in order as called in Javascript.

Build Date & Hardware: Build 22-08-17 on Mac OS Version 13.0 Beta (22A5321d)
Additional Builds and Platforms: Also not working on iOS 16 Beta

Doesn't Occur on Safari 15, latest Firefox and Chrome, Mac OS Version 13.0 Beta (22A5321d)
