From 5567d032784c615b8a8e3937d0eca24cedc70875 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Helen=20Hou-Sand=C3=AD?= Date: Tue, 3 Mar 2015 21:14:25 +0000 Subject: [PATCH] Nav menus: Better JS performance on initial load of edit screen. The accessibility helpers previously processed all items when editing a menu, which was quite slow to the point of being unresponsive for large menus. They now only process items when they are expanded or a user comes near them in some way, such as hover or focus. Also simplifies a redundant set of click event handlers down to one, which further enhances performance. props atimmer, sevenspark. fixes #25698.
