Match drag-drop schedule week view "shadow"
- When drag-dropping an item in the week view, the drop destination "shadow" highlights somewhere around the first 15 minutes of where the dropped item would end up.
- This works well when aligning the top of an item against another item, but when moving a tall item to be aligned along its bottom, the shadow is entirely useless and you need to in stead resort to carefully hovering the item where you want it before releasing.
- Suggest expanding the shadow to show the full height of the drop destination.
