Event: Don't break focus triggering after .on(focus).off(focus)#4885
Merged
Conversation
The `_default` function in the special event settings for focus/blur has always returned `true` since jquerygh-4813 as the event was already being fired from `leverageNative`. However, that only works if there's an active handler on that element; this made a quick consecutive call: ```js elem.on( "focus", function() {} ).off( "focus" ); ``` make subsequent `.trigger( "focus" )` calls to not do any triggering. The solution, already used in a similar `_default` method for the `click` event, is to check for the `dataPriv` entry on the element for the focus event (similarly for blur). Fixes jquerygh-4867
