Monitoring occasion latency requires an occasion listener. This precludes measuring occasion latency early in web page load and provides pointless efficiency overhead.
  • Expose Picture-in-Picture Window in leavepictureinpicture occasion: (Desktop solely) The leavepictureinpicture occasion now exposes a reference to pictureInPictureWindow in order that internet builders not have to hold a worldwide reference to that object.

When no such coverage is specified, Chrome will now use strict-origin-when-cross-origin as the default coverage, as a substitute of no-referrer-when-downgrade. On cross-origin requests made out of paperwork with out a specified referrer coverage, this reduces the Referer header to the initiating origin.
  • Update Fallback Content’s Behavior for ImageInputType and HTMLImageAspect: Changes the behavior of fallback content for ImageInputType and HTMLImageAspect. Such content material will now render precisely the identical as alt textual content would.
  • Update the Behavior of the “disabled” Attribute for HTMLLinkElement: Corrects several spec inconsistencies associated to the <hyperlink> tag’s disabled attribute. These behaviors are eradicated in compliance with a spec update.

The present writeValue() technique will stay for backwards compatibility, however its use is discouraged. The new APIs additionally don’t depend upon the GATT attribute properties being set accurately which permits working round buggy Bluetooth units.
  • WebAssembly MassiveInt Integration: WebAssembly now imports and exports WebAssembly perform parameters of sort i64 utilizing MassiveInt.
