Specification https://html.spec.whatwg.org/multipage/webappapis.html#event-loop-processing-model Summary Aligns Blink's dispatch timing for animation "transitionrun" event and media query "change" event with the spec, making the timing interoperable with Gecko and WebKit. More precisely, as per HTML window event loop specification, "transitionrun" events will be fired at Step 3.11 even for animations created earlier in the same iteration (instead of delaying them for a later iteration), and the media query "change" event will be fired at Step 3.10 before firing any pending animation events (instead of intermixing them with animation events at Step 3.11). Blink component Blink>Animation Web Feature ID No information provided Risks Interoperability and Compatibility Interoperability: no risk. This makes Blink interoperable with Gecko and WebKit. Compatibility risk: very low. The change only affects the relative order of media query "change" events and animation "transitionrun" events with respect to rAF callbacks, and this subtle timing adjustment is not expected to be noticeable to web applications. Gecko: No signal WebKit: No signal 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? No information provided Debuggability This feature is barely observable by developers, and is debuggable through event listeners and rAF callbacks. Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, ChromeOS, Android, and Android WebView)? Yes Is this feature fully tested by web-platform-tests?
