I think we're almost there, the spreading rest approach does work, and enableBackgroundUI will be passed down to the modal component. I'd just have a look at my other comments, as we can probably remove changes in 5 files total, and keep the changes limited to dialog.

I think adding some sort of test to verify the prop works, and create a baseline for the changes made would be beneficial. I'd take a look at the first playwright test in the sidebar pw file 👍
