[css-ui] appearance-disabling-properties should contain pseudoelements #9168
Description
Spec should include pseudoelements (::before and ::after) as properties that disable native appearance.
Current behaviour is not coherent:
- Chrome/Chromium already does that
- Webkit does too
- Firefox however doesn't, it requires
appearance: none;to be set to allow pseudoelements to exist.
Sample code:
<html>
<head>
<style>
.style-me::before {
content: "Hello";
}
</style>
</head>
<body>
<input type="checkbox" class="style-me" />
</body>
</html>Result:
Left – Chromium 115.0.5790.110
Center – Epiphany 44.2
Right - Firefox 115.0.2
Expected result:
Firefox has pseudoelement with content "Hello".
