wxiaoguang 345aa09756 Fix aria.js bugs: incorrect role element problem, mobile focus problem, tippy problem (#23450) ... This PR is extracted from #23346 to address some unclear (I don't understand) code-belonging concerns. This PR needs to be backported, otherwise the `aria.js` is too buggy in some cases. Since there would be two minor conflicts, I will do the backport manually. Before: the `aria.js` is still buggy in some cases. After: tested with AppleVoice, Android TalkBack * Fix incorrect dropdown init code * Fix incorrect role element (the menu role should be on the `$menu` element, but not on the `$focusable`) * Fix the focus-show-click-hide problem on mobile. Now the language menu works as expected * Fix incorrect dropdown template function setting * Clarify the logic in aria.js * Hide item's tippy after menu gets hidden * Fix incorrect tippy `setProps` after `destroy` * Fix UI lag problem when page gets redirected during menu hiding animation with screen reader * Improve comments * Implement the layout proposed by #19861 <details> d74a7efb60/web_src/js/features/aria.md?plain=1#L38-L47 </details>		3 years ago
