Cl listed at #9 got merged to M57 without approval. Also this is reported as P3, can't this wait until M58?

This merge is ok because it is only affecting WASM. The prio should be 1, because it is a planned prerequisite for the coordinated launch. I am wondering too why it was facilitated like that though.

I suppose you also might want to merge https://chromium.googlesource.com/chromium/src.git/+/85df088e0310cbb08280e453afc371faa01d0042?

Is this bug fixed btw?

Actually, you're right we need that one too, ok to merge?
