> I’m surprised you made a custom test here. I would have suggested instead doing a LayoutTests/perf test; those are designed to check that things are linear.

I didn't know about LayoutTests/perf. It is not immediately obvious to me how they are better but I'll move/refactor the test.

> But perhaps the number "20" here is related to the the number "20" in the assertion limit count for debug builds?

No it isn't.
