I tested it a bit and it's not 100% fixed.

If you select multiple elements, like several paragraphs with a block among them, then you paste it below, the issue is indeed fixed and the IDs are unique.

If you select a single block by clicking it and copying, then paste it like in the image below, then when you paste it will still have the same ID and copy the contents of the other block.

I also get a runtime error in the corner.
