Description
Expected Behavior
Dragging a stack of blocks looks similar regardless of the contents of the block stack.
Actual Behavior
On Edge, certain block stacks leave bits of shadow while dragging. The bits of shadow disappear when the drag gesture stops.
Steps to Reproduce
- Load
preview.scratch.mit.eduin Edge - Build this stack of blocks like this:
- Drag those blocks vertically upward.
- Note the trail under the blocks.
Operating System and Browser
Microsoft Windows [Version 10.0.15063]
Microsoft Edge 40.15063.674.0

Research direction
Start by reproducing the trail at preview.scratch.mit.edu in Microsoft Edge 40 using the custom-hat stack shown in the issue. Trace the drag rendering path for that stack and compare it with other stacks. Done means dragging vertically leaves no shadow trail and the existing behavior remains consistent across stack contents.
