@smfr: Do you think these should be under a runtime flag?

(In reply to Frédéric Wang (:fredw) from comment #2) > @smfr: Do you think these should be under a runtime flag? I tried to do both compile flag and preference setting, but builds fail so I think I'm missing something. This seems similar to that one though: [NotEnumerable, Conditional=FULLSCREEN_API, EnabledBySetting=FullScreen] attribute EventHandler onwebkitfullscreenchange;

Can we do overscroll and scrollend in two separate patches?

Please implement this. See : https://caniuse.com/?search=scrollend -- Safari is the only browser to not have implemented scrollend at this time

Hi! Happy to see this was enabled by default, but it looks like it wasn't included in Safari 26.0 or 26.1. Any news on when this will be available in user-land?

Try in a 26.2 seed.

Looks like this wasn't implemented in VisualViewport: > 'onscrollend' in HTMLElement.prototype < true > 'onscrollend' in Document.prototype < true > 'onscrollend' in VisualViewport.prototype < false Should we reopen this, or open a new bug?
