Constructor parameter shadows parent implicit val

Compiler version

3.3.0, 3.3.1-RC, 3.3.2-RC1-bin-20230703-0a21ecf-NIGHTLY-git-0a21ecf

Minimized code

class Conf

class Bar(_conf: Conf) {
  implicit val conf: Conf = _conf
}

class Foo(conf: Conf) extends Bar(conf)
//class Foo(_conf: Conf) extends Bar(_conf)
// using a different name fixes it

class Test {
  def test(foo: Foo) = {
    import foo._
    //implicit val conf: Conf = foo.conf
    // manually redefining it also fixes it
    assert(conf != null)
    assert(implicitly[Conf] != null)
  }
}

Output

-- [E006] Not Found Error: Test.scala:14:11 ------------------------------------
14 |    assert(conf != null)
   |           ^^^^
   |           Not found: conf

   | longer explanation available when compiling with `-explain`
-- [E172] Type Error: Test.scala:15:27 -----------------------------------------

Expectation

I expect it to compile cleanly, like it does in Scala 2.
