    <thetext>Hi Team,

Just another bug report based on Blink&apos;s comment and our failing test cases:

Failing Test Case - https://jsfiddle.net/wvsu7koh/show

Blink Commit - https://chromium.googlesource.com/chromium/blink/+/36890765b05b48d8065737682b4e878645b601b2

Webkit GitHub Source - https://github.com/WebKit/WebKit/blob/f3dfd0cc716eec21249cf1b3544fff9303053a0a/Source/WebCore/css/DOMCSSNamespace.cpp#L45

Just wanted to raise bug for future purposes. Thanks!</thetext>

    <thetext>To note, this is specifically CSS.supports (i.e., the JS-exposed API) and not @supports.</thetext>
