Specification Summary This proposal is to add an event that would fire on a content-visibility: auto element when the rendering state of the element changes due to any of the attributes that make the element relevant to the user ( https://www.w3.org/TR/css-contain-2/#relevant-to-the-user) Blink componentBlink <https://bugs.chromium.org/p/chromium/issues/list?q=component:Blink> Motivation The use-case for this is to let developers have greater control over when to stop or start rendering in response to the user-agent stopping or starting rendering of the content-visibility subtree. For example, the developer may want to stop React updates in a subtree that is not rendered by the user-agent. Similarly, the developer may want to stop any other script updates (e.g. canvas updates) when the user-agent is not rendering the element.

It poses minimal interop and compat risks, and can be feature detected and polyfilled *Gecko*: No signal ( https://github.com/mozilla/standards-positions/issues/664) *WebKit*: No signal (https://github.com/WebKit/standards-positions/issues/33 ) *Web developers*: No signals *Other signals*: WebView application risks Does this intent deprecate or change behavior of existing APIs, such that it has potentially high risk for Android WebView-based applications? Debuggability This feature can be debugged similarly to other events Is this feature fully tested by web-platform-tests <https://chromium.googlesource.com/chromium/src/+/main/docs/testing/web_platform_tests.md> ?Yes Flag nameContentVisibilityAutoStateChangedEvent Requires code in //chrome?False Tracking bughttps://bugs.chromium.org/p/chromium/issues/detail?id=1343432 Estimated milestones No milestones specified Link to entry on the Chrome Platform Status https://chromestatus.com/feature/5179553291436032 This intent message was generated by Chrome Platform Status <https://chromestatus.com/>. -- You received this message because you are subscribed to the Google Groups "blink-dev" group.
