Specificationhttps://drafts.csswg.org/cssom-view/#scrolling-events Summary Scrollend events help developers reliably tell when a scroll has completed (including both the scroll itself and any updates to offsets from the scroll). Knowing when a scroll has completed is useful for various reasons, e.g. synchronizing some logic on the snapped section, fetching stuff in a list, triggering new animations, etc. This feature greatly simplifies the logic for handling end-of-scroll effects, ensuring that they are consistent across many different input modalities. Currently, developers address this need by observing scroll events and building ad-hoc timeout algorithms.

Not potentially high risk. Debuggability We verified via Protocol Monitor that DevTools supports breaking on scrollend listeners, similar to other events. DevTools UI change is needed to make this accessible which will be done via crrev.com/c/4376080.

Please list open issues (e.g. links to known github issues in the project for the feature specification) whose resolution may introduce web compat/interop risk (e.g., changing to naming or structure of the API in a non-backward-compatible way).
