This is to prevent the rule-view from flickering when a new node is selected. This also makes the rule-vuew non-interactive (not responsding to user events) during the refresh time. If this takes too long, the rule-view is hidden after a delay. This also fixes a race condition in style-inspector-overlay's highlighters due to _hideCurrent being unnecessarily async. --HG-- extra : rebase_source : 87232abdd49cd149a482d6212aa80e960e8918c6
