Something crazy happened with the indentation here.

Is it possible for the WebCore code that has this expectation, and the ANGLE code that is expected to behave this way, to both predicate their behavior on a single bit? (so that they don't have to be kept in sync?). I guess that might be tricky since ANGLE can't use our feature macros.

Does not actually seem like you need this function on macOS proper.
