Bug 1529046 [wpt PR 15421] - CDC versus Ident Token, a=testonly Automatic update from web-platform-tests CDC versus Ident Token Tests <https://github.com/w3c/csswg-drafts/issues/3623>. If the CDC-vs-ident check is performed in the wrong order, you will attempt to parse the CDC as an ident instead, emitting a `--` ident token, and then a `>` delim token. Thus, if this test is parsed incorrectly, it'll instead think the selector is `-- > --foo`, a valid selector with two tagname selectors separated by a child combinator. -- lint: remove trailing whitespace -- Merge pull request #15421 from web-platform-tests/tabatkins-patch-2 CDC versus Ident Token -- wpt-commits: c79dbe6d777590620087aadbceb07668d3f2fd89, bf1be2ec37487a34adb4ac2ca75b7a061d27b8fe, 542f927a85e239ae514db33e73d4421f86b267ae wpt-pr: 15421
