Description

The before and after pseudo-elements don't have a background-colour (I haven't checked for other properties) when they don't have a display assigned.

<!DOCTYPE html>
<html lang="en">
<body>

    <style>
        .with::after {
            display: block;
            background-color: #FF7500;
            content: "Some content";
        }
        .without::after {
            background-color: #FF7500;
            content: "Some content";
        }
    </style>

    <div class="with">With</div>
    <div class="without">Without</div>
</body>
</html>

Contributor guide

Research direction
Examine how pseudo elements are handled in the CSS rendering pipeline, specifically the default display value and how background properties are applied. Look for missing display assignment for inline elements.
