The error in your emitter example is correct, because K can be a union type, so event and listener can have incompatible types. Same issue as #57691 and many many others.
The first error is most likely simply due to the deferred resolving of conditional types when they involve an unbound generic type. The compiler has no idea what the types K or T are, so it can't know what type Foo<K, T> resolves to. A known design limitation.

Closing because this needs #27808 (a oneof qualifier).
