Looks like Chrome has the same bug so that's a bit concerning... Created attachment 434729 [details]

Comment on attachment 434729 [details] Patch View in context: https://bugs.webkit.org/attachment.cgi?id=434729&action=review >> LayoutTests/ChangeLog:13 >> +2021-08-01 Ryosuke Niwa <rniwa@webkit.org> > > double change log. Weird. Not sure what happened here. Will fix before landing. Committed r280551 (240178@main): <https://commits.webkit.org/240178@main> This might be a spec misunderstanding: From the spec: [[activeTargets]] represents all Elements whose size has changed since last observation broadcast that are eligible for broadcast. What makes an element eligible is not explicitly defined. My intuition is that calling "unobserve" on an elment should make it inelligible.
