Automatic update from web-platform-tests Make custom properties that are IACVT guaranteed-invalid (II) Per recent spec change [1], custom properties that are invalid at computed-value time (IACVT) shall become guaranteed-invalid [2] if the custom property supports guaranteed-invalid values. In order to maintain our current animations behavior related to cycles (see CSSVarCycleInterpolationType), we still need to be able to distinguish between "cyclic" and "invalid for other reasons" from the outside. These two situations are now represented by CSSCyclicVariableValue and CSSInvalidVariableValue, respectively.
