I don't want to change the close event to touchstart, click is the right one. cristian also doesn't like it when we attach to touchstart - since that way users can't "cancel" their action by moving their finger away. and I kind of agree with him... attaching button events to touchstart feels a bit weird.

the alternative I thought of could be to just change the pointer-events to 'none' on the Close button, when in edit mode. do you prefer that?
