These are cases that are implementing the "convert an exception to a Promise" steps of the Web IDL spec. Typically the exception is thrown in the current compartment; the Promise returned should simply match that. Otherwise we can end up with a situation in which the promise doesn't actaully have access to its rejection value, which will cause problems if someone uses then() on the promise: the return value of the then() call will get a sanitized exception instead of the real one. We _could_ try to match the actual compartment of the exception, in theory. But it's not clear why this would be preferable to using the current compartment, even if there were cases in which the exception _doesn't_ match the current compartment. Which there likely are not.
