Gesture simulation for "move" does not function correctly in IE10 and Phantom.js

IE10 reproducible test @ http://jsbin.com/uzajan/1

An initial investigation hasn't turned up anything conclusive, so more work to find the root cause will be required.

Note: When testing this issue in IE, ensure that Browser Mode and Document Mode are set to "IE10" and "Standards/Quirks Mode". IE10 with a Standards Mode set to "IE9 Standards" will behave correctly.

This failure occurs in ie11 (win7 and win8.1) as well.
