Status: RESOLVED FIXED

(Core :: Layout, defect)

Description

[Ksenia Berezina [:ksenia] on leave until 09/15]

As reported in https://github.com/webcompat/web-bugs/issues/78699 search results are not showing on https://www.gobros.com/collections/running-training-socks/women in Nightly 91.0a1 (2021-07-05)

The site is using content: none on non-pseudo elements:

div.snize-search-results ul li {
    list-style: none;
    content: none;
}

We've got a couple more reports similar to this, so creating this bug to track them.

Hi Mats, adding a ni here

We should probably disable it by default for now and go back to the csswg or something.
