2THIS LIBRARY HAS BEEN MANUALLY PATCHED TO SOLVE AN ISSUE WITH iOS; DON'T UPDATE WITHOUT REAPPLYING.
3iOS would not register clicks on inputs inside draggable blocks, e.g. emoticons management. Fix:
4
5//line: 31    
6function simulateMouseEvent(event, simulatedType) {
7 	//...
8	//changes to add ++
9	if ($(event.target).is("input") || $(event.target).is("textarea")) {
10	    return;
11	} else {
12	    event.preventDefault();
13	}
