Bug Report

Current Behavior
Calling t.super() results in a compile-time type error, as super isn't present in type definitions. It does exist in the documentation and works as expected after compilation.

Expected behavior
The super method should be present in the type definitions.

As someone using TypeScript to minimize errors, the amount of casting is extremely verbose. By itself, that's not an issue, but coupled with errors in type definitions (this along with #10065) are forcing the use of unsafe casts and // @ts-ignore.
