@c4rl0sbr4v0 I reverted the revert of https://core.trac.wordpress.org/changeset/54333 in https://core.trac.wordpress.org/changeset/54370.

The JS side of this is in the GB packages, and will need another build sync for 6.1 Beta 3 tomorrow.

Thank you! This seems to reflect the changes from this Core commit well (except for one minor discrepancy).

We might have to file another PR to apply changes suggested by @spacedmonkey (1, 2, 3); I think @dream-encode has filed a PR against wordpress-develop: WordPress/wordpress-develop#3404. So we can wait for that PR to land and then file a PR to carry those changes back over here.
