Here is an interactive exercise with a Parsons problem:
When the page first loads, the Parsons blocks render as expected. But as the page load completes, the blocks overlap: each block gets partially hidden behind the one below it.
Is this intended behaviour? It makes it hard to see what is on each block.
Once I try to drag a block, the blocks expand again, but then they overflow the block containing the exercise.
Maybe I'm just not supposed to make a Parsons problem this long?
