No "unreachable code" warning when using partial function syntax

[sake92]

Compiler version

3.*

Minimized code

object PartialFunctionNoWarning {

  // nice warning
  "abc" match {
    case "abc" =>
    case "abc" =>
  }
  
  // no warnings
  val pf: PartialFunction[String, Unit] = {
    case "abc" =>
    case "abc" =>
  }

}

Output

"unreachable code" when using match.

Expectation

"unreachable code" shows when using partial function syntax too.
In scala 2 it does show a warning.

Good news! This appears to be fixed in 3.3.1-RC7 (so will be in 3.3.1) and on main.

Sorry @bishabosha, I think I filled in the labels at the same time as you, causing the mess above
