Calendar Widget: remove the title attribute for days and replace with aria-label. Spruce up some of this nasty code. Delete unnecessary bits.
Props wonderboymusic, elusiveunit, 5um17. Fixes #30297. Built from https://develop.svn.wordpress.org/trunk@34463 git-svn-id: http://core.svn.wordpress.org/trunk@34427 1a063a9b-81f0-0310-95a4-ce76da25c4cd
