Highlight in edit selector take too much time

The new highlight in UiExplorer is so good because it gives you the control to launch and stop highlighting whenever you want, in contrast the highlight in edit selector is not working in the excpected way because it highlight the element but take to much time to stop this, I think it should work like the UiExplorer but when clicking on highlight in edit selector for some activity it just freezes and and you stuck there for 10-15 seconds which get a little bit uncomfortable while developing.
thank you for checking this out.
