Summary REGRESSION (iOS 18): Removed DOM elements still visible

Reported 2024-10-09 13:38:53 PDT
Created attachment 472886 [details] Video comparing iOS 18 and iOS 17.5 I've experienced a regression in iOS 18 with some DOM elements still being visible after they've been removed from the DOM tree. In the example video, our calendar event "laban" should only be visible on "Torsdag". Sorry about the very specific example, I'm not sure how to begin to recreate this behaviour as I haven't seen it in any web browser before.

Thank you for the report! Would you be willing to share whether this affects any live websites or shipping apps?

It does impact a live website and an app which uses that website. I can give a testable environment with a one-time password, to the person(s) would like to see it or inspect it live.

The website https://business.itswavy.com/ requires a login. Robin indeed without an access we can't really do anything. Except if you manage to create a reduced test case. What is the behavior on Android?

I got around the issue by applying the CSS-property: will-change: transform; to the containing element. It stopped the rendering issue from occurring. I'll try to make an reproducible example.
