Looks good! Could you squash the commits into one single commit, too?

[KaczuH]

Ok, commits are sqashed.
I'm not sure why AppVeyor build was cancelled.

Yes, that worker failure is caused by #21350 and should be fixed by #23322.

oh, thanks! didn't notice that! then just need to update expectation for the PASS one! thanks!

[jdm]

We need to adjust the from_resource_timing method below this to initialize the value to the stored one as well.

[KaczuH]

Ok, done :)

[jdm]

Sorry about the delay in reviewing this!
