Looks like a runnable scheduled by nsDocument::ScheduleIntersectionObserverNotification. Does NewRunnableMethod add a reference to the document? Otherwise nothing is keeping the document alive while we wait to run the runnable and could be running in a free'd document?

(In reply to Timothy Nikkel (:tnikkel) from comment #1) > Does NewRunnableMethod add a reference to the document? Yes it does. There's a comment above NewRunnableMethod that says: "MyClass must define AddRef and Release methods" http://searchfox.org/mozilla-central/source/xpcom/glue/nsThreadUtils.h#840
