There are some test failures, but they don't seem to be the result of this PR. In fact, there are some test failures in the HEAD of the wp/6.5 branch.

Let’s give it a try. Thank you for crafting these changes. It looks like CI is failing also because of reports related to outdated config for browserlist. This is something that probably should be disabled on old branches.

Can we close the issue now?

Thanks for the review! Yes, #62780 can be closed.
