Dragline keeps flickering when dragging item

[mboudreau]

Describe the bug If you look at your own demo, if you go between items and the drag line appears, if you move your mouse horizontally, it'll often times flicker even though the position of the item to be dropped hasn't change. The dragline should remain "stable" during this time. It's almost like the whole tree rerenders when dragging an item.

To Reproduce Drag an item in your own demo page.

Expected behavior Dragline should remain stable while moving the mouse between items. I have a feeling this is an issue with re-rendering when nothing's changed. It's also weird to use a function to get the styling instead of just passing the static styles on change from the hook, which might be the crux of this issue...
