reveal_type not run in "unreachable" branches

[hjwp]

Bug Report

It looks like reveal_type() doesn't work in "unreachable" branches, ie places where assert_never() passes.

To Reproduce

from typing import assert_never, reveal_type


def foo(b: bool):
    reveal_type(b)
    match b:
        case True:
            reveal_type(b)
            print("True")
        case False:
            reveal_type(b)
            print("False")
        case _:
            assert_never(b)
            reveal_type(b)  # this one does not print

Actual Behavior

❯ mypy thing.py
thing.py:5: note: Revealed type is "builtins.bool"
thing.py:8: note: Revealed type is "Literal[True]"
thing.py:11: note: Revealed type is "Literal[False]"
Success: no issues found in 1 source file

Expected behaviour

I would expect the 4th reveal_type() to print something like Revealed type is Never ?

(note that the assert_never() does "pass").
