  "message": "Allow downcasting CSSLightDarkValuePair and CSSParamValuePair to CSSValuePair\n\nCSSLightDarkValuePair and CSSParamValuePair derive from CSSValuePair,\nbut DowncastTraits\u003cCSSValuePair\u003e checks CSSValue::IsValuePair(), which\npreviously only checked for kValuePairClass. As a result, downcasting\nvia To\u003cCSSValuePair\u003e failed a CHECK in casting.h when called on\nderived instances (such as in CSSValue::HasRandomFunctions() when\nevaluating light-dark() animations for compositing).\n\nFixed: 561828148\nChange-Id: I2a6777553314dcd605b4767de97db6cb7bc16886\nReviewed-on: https://chromium-review.googlesource.com/c/chromium/src/+/8410130\nAuto-Submit: Munira Tursunova \u003cmoonira@google.com\u003e\nCommit-Queue: Rune Lillesveen \u003cfuthark@chromium.org\u003e\nReviewed-by: Rune Lillesveen \u003cfuthark@chromium.org\u003e\nCr-Commit-Position: refs/heads/main@{#1699576}\n",
