Drag Source Remounts with Correct Props

Regression example based on #1429 that verifies that as drag-sources are remounted, they receive their correct props from React-DnD.

The box at the drag-source location should flash red while the item is being dragged around.

<view-source name="07-regression/remount-with-correct-props" component="other-remount-with-correct-props"> </view-source>
