Issue can be replicated with this demo: https://stackblitz.com/edit/wqbm8k-w4zg5t
Replication steps:
When the node is dropped to the swimlane, the node's z-index is automatically adjusted to be higher than the swimlane (which is great functionality), but it would be nice that already during the hovering the node stays visible (which is what it will be visually when the dropping is completed).
One thing to note is that user will end up to that z-order when the node is added to the diagram before the swimlane.
The attached video also demonstrates the issue.
