Attached file testcase 1

This is probably just be a case where the values are larger than what we can handle (i.e. a version of bug 265084). It seems to work fine if I adjust the heights to be more reasonable sized. (not ~10million pixels tall)

Note that the text does not even paint at the bottom of the original website & at the bottom of my attached testcase, in my Nightly profile, for some reason. (It does paint in a fresh profile, though. Anyway, that's beside the point from the scrolling issue.)

Priority: -- → P4

Still manifests 80.0b4.

Reproducible on Nightly 81.0a1 (2020-08-19) on macOS 10.14. Updating flags accordingly.

Severity: normal → S4
