Avoid crash when adopting nodes with event listeners #39901

TimvdLippe · 2025-10-15T15:17:28Z

Previously we would crash when the event listener runs in the new document, since it was compiled against the global from the old document. Instead, we need to mark all event listeners as uncompiled, so that we reset the global to the new document.

It also adds a new WPT test, but it is named tentative since Chrome and Firefox differ in behavior.

Fixes #36397

+      img.addEventListener('load', () => {
+        assert_equals(window.imageLoaded, false, "Window should point to iframe contentWindow");


The message here is confusing, since it seems to contradict what the test is checking. Doesn't the iframe content window have imageLoaded=true because the element's onload handler executes before the iframe's load event is fired?

I am not sure what the expected behavior should be and opened whatwg/html#11795 to discuss that. Seems like Chrome and Firefox disagree as well on what this should be.

✨ Try run (#18780227858) succeeded.

Previously we would crash when the event listener runs in the new document, since it was compiled against the global from the old document. Instead, we need to mark all event listeners as uncompiled, so that we reset the global to the new document. It also adds a new WPT test, but it is named tentative since Chrome and Firefox differ in behavior. Fixes servo#36397 Signed-off-by: Tim van der Lippe <tvanderlippe@gmail.com>
