Bug 245205 – Align "UA" stylesheet for hidden elements with HTML Spec and consolidate "display: none"

• Status: RESOLVED
• Resolution: FIXED
• Component: CSS

[Ahmad Saleem]

I noticed that we are failing few WPT tests:

https://wpt.fyi/results/html/rendering/non-replaced-elements/hidden-elements.html?label=master&label=experimental&aligned&view=subtest&q=hidden%20element

Because we don't have those elements defined as "display: none" in html.css like other browser engines 'Gecko' and 'Blink'.

This bug is to add the missing and also consolidate already used 'display: none' in one go to make it easier to read and manage.

I am going to follow web-spec:

https://html.spec.whatwg.org/#hidden-elements

In case, if I am not able to do it and had to close my PR, I will share details on genuine test failures or why this is no go at the moment for Webkit so someone else can take a look in future.

Thanks!
