webmail: fix dragging the corner of the compose popup when it's on top of a message view with an iframe (for an html message)

Browse source 
the pointer events for moving the mouse would be consumed by the iframe. that
broke resizing of the compose popup.  we now disable pointerevents on the main
ui when we are dragging the corner of the compose popup.

this is similar to an earlier change about the draggable split bar between the
message list and the message view (when showing an html message).
