Description Jean-Yves Avenard [:jya] 2023-05-19 09:12:36 PDT 
When you call `addSourceBuffer` on a ManagedMediaSource you actually get a `ManagedSourceBuffer`; however as far as the JS binding is concerned, the object looks only like a `MediaSource` and none of its IDL methods are actually usable.

The appropriate custom `toJS` methods are missing and so the wrong JS wrapper type is created (a JSSourceBuffer instead of JSManagedSourceBuffer)
