These changes fix the selector used by block instance element styles for links so they do not get incorrectly applied to buttons. Props aaronrobertshaw, freewebmentor, mukesh27. Fixes #60557. Built from https://develop.svn.wordpress.org/trunk@57664 git-svn-id: http://core.svn.wordpress.org/trunk@57165 1a063a9b-81f0-0310-95a4-ce76da25c4cd
