Comment 1

[Mirko Brodesser (:mbrodesser-Igalia)]

Depends on bug 1824374 because one subtest uses popovertarget.

The other currently failing subtests use and hence depend on the anchor attribute which belongs to the CSS Anchor Positioning (https://drafts4.csswg.org/css-anchor-position-1/), which isn't implemented in Gecko yet.

Comment 2

The sub-test failure is related to Anchor positioning, which is not yet supported in Gecko.
