connectDragPreview: preview image broken in Microsoft Edge Browser

[lkuettner]

When looking at the examples (e. g. https://cormacrelf.github.io/angular-skyhook/examples/index.html#/html5/handles-previews), the preview image dosn't show up in Edge (v42.xxx) or is way too small (v44.xxx). This is unlike Angular CDK Drag and Drop (https://material.angular.io/cdk/drag-drop/overview) where everything seems to be working fine.

I don’t have a windows machine to test it on, and given that EdgeHTML is being replaced with Chromium guts, I’m not sure this is even worth attempting to fix. Nevertheless, you might find something for it on https://github.com/react-dnd/react-dnd, which is where that code lives.
