Bug report

Since 1.3.0, PHPStan started reporting this strange error in our codebase. A type of $this(ArticlesTable) is inferred for a type parameter but then rejects a value of type ArticlesTable which is a final class. Funnily enough, making the class non-final yields no errors.

Expected output

No error.
