script: Implement DocumentOrShadowRoot.FullscreenDocument by onsah · Pull Request #42401 · servo/servo

onsah · 2026-02-06T11:57:32Z

Implement DocumentOrShadowRoot.FullscreenDocument.

Changes

Update IDL definition by removing Document.fullscreenElement and declaring it in DocumentOrShadowRoot mixin as per the spec
Implement fullscreenElement getter as a method in DocumentOrShadowroot.get_fullscreen_element which is used by Document and ShadowRoot.
Changedbubble and composed flags for fullscreen enter and exit events to true.
Delete shadowroot-fullscreen-element.html.ini since the test now passes.

Testing

Enable shadowroot-fullscreen-element.html WPT test.

Passing WPT run: https://github.com/onsah/servo/actions/runs/21872882492

⚠️ Try run (#21811194081) failed!

Looking good! Some suggestions.

We just need to check the reason for the failure, which I believe related to the non-compliant fullscreen element.

@@ -4599,7 +4601,7 @@ impl VirtualMethods for Element {

        let doc = self.owner_document();

-        let fullscreen = doc.GetFullscreenElement();
+        let fullscreen = doc.fullscreen_element();
        if fullscreen.as_deref() == Some(self) {


This change was necessary to fix the test regressions. I suspect the reason was because now Document::GetFullscreenElement is implemented as per the spec, which may return null if the fullscreen element is removed from the document while Document::fullscreen_element is still pointing to the removed element. Changing it to return the Document::fullscreen_element field fixed the failing tests.

Thanks! LGTM with a nit.

+        let retargeted = fullscreen_element?
+            .upcast::<EventTarget>()
+            .retarget(node.upcast());
+        let candidate = retargeted.downcast::<Element>().unwrap();


This unwrap is scary. Please add a comment that it's okay because the retarget algorithm returns either fullscreen_element or a shadow host in its list of shadow-including ancestors, and all of those are elements.

Added this comment:

It's safe to unwrap downcasting to Element because retarget either returns fullscreen_element or a host of fullscreen_element and hosts are always elements.

Details such as shadow-including ancestors seem like not essential here as any kind of host is always an element.
