Custom Events and Typescript

[andrewtimberlake]

I don’t know if this is Glint or Ember related.

When creating a function to handle a custom event, Glint complains that the signature doesn’t match. The signature expects an Event rather than a CustomEvent
When creating a function to handle a mouse event {{on "click" this.handler}}, the signature for this.handler correctly expects a MouseEvent

@andrewtimberlake actually I think this is not related to Glint nor Ember, this is just a problem in Typescript in general.
You can see microsoft/TypeScript#28357 (comment) for a possible solution
