As of Fx108, I intend to turn "the support of width/height attributes on source elements" on by default on all platforms. It has been developed behind the *dom.picture_source_dimension_attributes.enabled* preference. Status in other browsers is: Chrome and Safari have shipped this already.
*Bug to turn on by default*: https://bugzilla.mozilla.org/show_bug.cgi?id=1795953 Standard: https://github.com/whatwg/html/pull/5894 and https://html.spec.whatwg.org/multipage/embedded-content.html#the-source-element This feature was previously discussed in this "Intent to prototype" thread: https://groups.google.com/a/mozilla.org/g/dev-platform/c/V0nhaTr86LA/m/aH-jZUqzAAAJ Thanks -- You received this message because you are subscribed to the Google Groups "[email protected]" group.
