For instance step 8 and 9 of decrypt() state:

https://w3c.github.io/webcrypto/Overview.html#dfn-SubtleCrypto-method-decrypt

8. If the name member of normalizedAlgorithm is not equal to the name attribute of the [[algorithm]] internal slot of key then throw an InvalidAccessError.

9. If the [[usages]] internal slot of key does not contain an entry that is "decrypt", then throw an InvalidAccessError.

Chrome does the checks in the opposite order.

.... technically the result is still spec-compliant since in both cases an InvalidAccessError is returned, however the error message will contradict the presumed ordering.
