Subject: [PATCH] Fix issue with pasting in IE11 (#1901)

* Fix issue with pasting in IE11

Fixing the issue where dataTransfer or clipboardData are not populated,
in IE 11 under event.NativeEvent. Instead, if we are using IE11, use
the base event object instead which contains a valid dataTrasnfer/clipboardData object.

* Run prettier on code changes
