[markglattback]

The following code is incorrectly highlighted when using the new const Type Parameters with TS 5.0.x and Volar 1.3.8 (pre-release)

function myFunc<const T extends string[]>(arr: T): T {
  return arr
}

//  error: Type parameter declaration expected. ts(1139)

This is a VSCode issue, and it should be fixed in the latest VSCode release.
