Occasionally the workflow for “when something is dropped” will fail. (And the “hovered” state will stay on. )
(This is in reference to the drag and drop plugin that bubble makes.)
I learned this only happens when the drag and drop component is made using the new responsive engine by making two otherwise identical components; one running on the old responsive engine (in a reusable element) and the other using the new responsive engine. Both were placed on a page which is running on the new responsive engine. (The one which was built using the new responsive engine was built on the page while the other was in a reusable element.) Only the reusable element version (running on the old engine within it’s own element) did not have the occasional failure.
