Change-Id: Iff53a803596f4fc1eae8e4bfa307b9c1f4df961a

* Fixed drag and drop failure when message dragged from email client (#20451)

When dragging message form email client on Windows, item.webkitGetAsEntry()
might return null creating NPE on the client side. Added additional checks
for this situation.

* Fixed touch scrolling issue in Surface and WP devices (#18737)

Fixed by using pointerevents instead of touchevents when the browser is
IE11,
or Edge. Also added touch-action: none; css rules into escalator.css to
prevent
default touch behaviour on IE11 and Edge. Does not affect IE8 to IE10
browsers,
behaviour on those will stay the same as before the fix.

No new unit tests since we do not have automatic touch testing
possibilities yet.
Please test manually with Surface: IE11 and Edge, use for example
uitest:
