Selector: Remove the "a:enabled" workaround for Chrome <=77

mgol · web-flow · commit c1ee33aded44 · 2019-12-16T19:43:38.000+01:00
Remove the workaround for a broken `:enabled` pseudo-class on anchor elements in Chrome <=77. These versions of Chrome considers anchor elements with the `href` attribute as matching `:enabled`. Closes gh-4569
