1658946 - Make resolving a promise with an XPCOM type more usable.

Status: RESOLVED FIXED

(Core :: XPCOM, enhancement)

Description

[Emilio Cobos Álvarez [:emilio]]

Right now stuff like this goes through this ToJSValue overload which doesn't pass an IID so it ends up causing us write code like this, which is not great. Ideally you wouldn't need the extra QueryInterface there if the interface is not ambiguous or if you pass a concrete interface type.

Attachment: Bug 1658946 - Wrap non-wrappercached interfaces more precisely in ToJSValue,

This will allow resolving DOM promises with non-wrappercached XPIDL interfaces
in a more convenient manner, as the wrapped JS object will have more concrete
interface information without needing to invoke QueryInterface.
