layout: Treat `<audio>` as replaced and do not display when there is no `controls` attribute by Loirooriol · Pull Request #41262 · servo/servo

Loirooriol · 2025-12-14T22:45:02Z

Add an important UA style to ensure that <audio> isn't displayed at all when it doesn't have the controls attribute. This matches Gecko, Blink and WebKit.

When it does have the attribute, then treat it as replaced. For example, this means that it won't stretch by default if it's block-level, that it will be atomic if inline-level, and that it won't generate boxes for its children (including ::before and ::after).

Previously we were generating ::before and ::after, but there was a bug: if they had some replaced content, the controls of the <audio> would be duplicated, and also appear on the pseudo-element. Then, since the various boxes for the controls would be backed by the same elements, Servo could panic because of a double borrow. This is now avoided.

Testing: Some WPT are now passing, also adding a new crashtest. There is one failure about innerText, but the test is probably wrong, now we match other browsers.

✨ Try run (#20229729677) succeeded.

Add an important UA style to ensure that `<audio>` isn't displayed at all when it doesn't have the `controls` attribute. This matches Gecko, Blink and WebKit. When it does have the attribute, then treat it as replaced. For example, this means that it won't stretch by default if it's block-level, that it will be atomic if inline-level, and that it won't generate `::before` or `::after`. Previously we were generating `::before` and `::after`, but there was a bug: if they had some replaced content, the controls of the `<audio>` would be duplicated, and also appear on the pseudo-element. Then, since the various boxes for the controls would be backed by the same elements, Servo could panic because of a double borrow. This is now avoided.
