Notes

These updates will be on mozilla-central once bug 1693114 lands.

Note: this bug is for tracking fixing the issues and is not
owned by the wpt sync bot.

This bug is linked to the relevant tests by an annotation in
https://github.com/web-platform-tests/wpt-metadata. These annotations
can be edited using the wpt interop dashboard
https://jgraham.github.io/wptdash/

If this bug is split into multiple bugs, please also update the
annotations, otherwise we are unable to track which wpt issues are
already triaged. Resolving as duplicate or closing this issue should
be cause the bot to automatically update or remove the annotation.

It looks like the presence of will-change: transform; in the testcase is interfering with background-attachment: fixed; here.

Looks like this always failed, just changed between failing and timing out. I probably won't have time to dig into why in the near future.
