My comment shouldn't block you but please update the changelog entry.

This seems wrong 🤔

[gagik]

Huh weird, not sure how I didn't get much errors or anything; the sleep above is also referring to a level above it should. created PR for these: #6833

[kraenhansen]

Not a fan of forEach as it's not obvious that the callback is called synchronously.

[gagik]

actually this function itself doesn't have to be defined as async, would that be okay then?

[kraenhansen]

I'd rather that this was a for-of loop. I personally never use the forEach for this reason (that no guarantees are made on how the callback is invoked and this code expects it to be invoked synchronously).

[kraenhansen]

I'm sure this could be written without the type assertion 🤞

[gagik]

unfortunately not, it thinks of itself as an array of (ProgressMode | ProgressDirection), I wish typescript was a little smarter.

[kraenhansen]

An as const seems simple enough: https://www.typescriptlang.org/play/?#code/KYOwrgtgBACgTgewOZ2AZzQWQQE2FAbwCgooAlYABwTgBcBJEPAMwEsRXbgAbATwBoSUAGI0AwmDioQtPgHkwtNLQCGTdkgDqNANaCAvkVCRYiFOjQARVqgDGtVghCEhlhAHcQ3BCpyDSAKqU3r4GRES2TspQAG4q3GDoUAC8UADaRAD0maSkAHoA-EJp8MioGNh4AHQU1HSMLOycPAKmZRbWdg5OVW6eITgAuv7ppeYVuMA1VDQMTMBsHFx8-G3jVjbA9o4gVUEDw8Vj5ViTVaJwElKgsrwKSqrqIFq6q8cdm9s9fV4+QyMlMwnSpTC5XaS3e7KNQ4DTaOB6NYnTpbbq7fZ-Q6DKAqNBQSIgZQAbiIQA

Oh cool! I remember using as const before but dind't think of this in that scenario
