fixes #3522. Not sure why it took so long for this solution to occur to me (apologies if anyone had already suggested it) — all we need to do is guarantee that SVG spread attributes are only ever set with
setAttribute
, and we're good.The test here is harmless, but also useless — JSDOM doesn't error when you try to set readonly properties, and I can't be bothered to raise an issue.
