Note that since no template parameters are supplied here, the type will be Bridge<any, any>. As a result, for calls to on and call, TS won't even check if the first argument is a string.

Passing in the bridge here is not really the best separation of responsibilities. What I would suggest we do in future is make the sidebar responsible for listening for the message and instead put only the logic for updating the page elements (the contents of updateAnnotationCountElems here) in a function in a separate module.

The issue about any type doesn't seem to happen in version 4.5:

I agree.

Are these typedefs still needed given the change to the Bridge typedef above?
