Description Simon Pieters (:zcorpan) 2022-02-16 12:46:35 PST
What steps will reproduce the problem?
(1) Open data:text/html,a<layer>b

What is the expected result?
"ab" should be on one line (because <layer> should be display:inline)

What happens instead?
"a" and "b" are on separate lines (because the UA stylesheet has layer { display:block })


This is in violation with the HTML standard which doesn't say <layer> should have any UA style: https://html.spec.whatwg.org/multipage/rendering.html#rendering

Chromium also has this bug (https://bugs.chromium.org/p/chromium/issues/detail?id=1298197 ), but not Gecko.
