Script Editor gives inappropriate "unreachable code detected" warning

[HauntedBees]

Godot version

v4.0.beta13.official [caacade]

System information

Windows 8.1

Issue description

The Unreachable code (statement after return) in function 'function_name()' warning is given for functions that do not have unreachable code. The same code does not give this warning in v3.5.stable.official [991bb6a].

Steps to reproduce

func warning(i: int) -> void:
  if i == 0:
    pass
  elif i == 1:
    return
  else:
    return
  print("yeah")

Removing either the elif or the else removes the warning.

Minimal reproduction project

N/A; code in reproduction steps can be placed in any blank gdscript file to trigger the error.
