To be able to disable jQuery Migrate as step 3 of updating the jQuery version shipped with WordPress, all `JQMIGRATE` warnings in the browser console will have to be addressed. This includes many minor adjustments to a wide array of core files. Follow-up to: * Step 1: Disabling jQuery Migrate 1.4.1 in WordPress 5.5: [48323], [48324] * Step 2: Updating jQuery to 3.5.1 and adding jQuery Migrate 3.3.x in WordPress 5.6: [49101], [49338], [49615], [49649] Props Clorith, azaozz.
