Table rows don't seem to be sortable in IE (edge and others)

`tr`s, and things styled with `display:table-row` don't seem to work correctly in IE

They work perfectly in chrome/safari/firefox.

In IE the `tr` is draggable, but when moving the `tr` over the other rows the "spacer row" doesn't follow, it just stays where you dragged the `tr` from.

There are no console errors, I assume some difference of when/how events happen to do with TRs.
Dragging `div`s around works perfectly in our same setup and versions of everything.

(I'm having trouble getting the the issue template jsfiddle working, I can make a failing case once I have something working to build on)
