Specificationhttps://drafts.csswg.org/cssom/#dom-window-getcomputedstyle Summary The pseudo element argument in some APIs ( getComputedStyle(element, pseudo) and new KeyframeEffect(target, keyframes, {pseudoElement}) is currently parsed in a way that doesn't match the spec - e.g. it allows pseudo-elements without ":", it doesn't parse whitespace correctly if there is argument, and several other issues. There are many failing tests around this. Recently webkit fixed this to more closely match the spec. Proposing to modify the behavior to match the webkit implementation and the spec, un-skipping most of the tests. Using a chromestatus entry for this as it's a web-facing behavior change.

Activation This should be mostly compatible with existing usage. Security N/A 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? N/A Debuggability N/A 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 <https://chromium.googlesource.com/chromium/src/+/main/docs/testing/web_platform_tests.md> ?Yes This mainly captured in the following two tests, that should be mostly unskipped after this change. https://wpt.fyi/results/css/cssom/getComputedStyle-pseudo-with-argument.html https://wpt.fyi/results/css/cssom/getComputedStyle-pseudo.html Flag name on chrome://flagsCSSComputedStyleFullPseudoElementParser Finch feature nameCSSComputedStyleFullPseudoElementParser Requires code in //chrome?False Tracking bughttps://issues.chromium.org/issues/328470598 Adoption expectationIt's not a widely use feature, but mostly because it's been incompatible across browsers for a long time. With view-transitions making more use of pseudo-elements this will likely become more important.

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).
