A WebIDL callback interface is allowed to have constants

• Component: Bindings
• Status: RESOLVED FIXED

[Chris Dumez]

A WebIDL callback interface is allowed to have constants. Currently, our bindings generator does not support that.

Spec for constants:
https://heycam.github.io/webidl/#dfn-constant

Part about constants and callback interfaces:
https://heycam.github.io/webidl/#es-user-objects
"The [NoInterfaceObject] extended attribute must not be specified on a callback interface unless it has a constant declared on it. This is because callback interfaces without constants never have interface objects."

The callback interface should also have a corresponding property on the global object if they are constants:
