"Extract Method" changes the behavior of a VB.NET program

[severity:It’s more difficult to complete my work]
Repro steps:

1. Create the following VB program:

Public Module Module1
    Public Sub Main()
        Console.WriteLine("A")
        If Math.Abs(1) = 1 Then Return
        Console.WriteLine("B")
    End Sub
End Module
  

Note that this program outputs “A”.

2. Select the first two lines inside Sub Main and use the “Extract Method” refactoring tooltip. This creates the following program:

Public Module Module1
    Public Sub Main()
        NewMethod()
        Console.WriteLine("B")
    End Sub
    
Private Sub NewMethod()
        Console.WriteLine("A")
        If Math.Abs(1) = 1 Then Return
    End Sub
End Module
  

Expected result: The new program behaves exactly like the old program.
Actual result: The new program outputs both “A” and “B”.

This is a bug, since the “extract method” refactoring should not change the behavior of the program. It seems to be a VB. NET-only issue, since the same refactoring works fine in the equivalent C# code (creating a method that returns a “flowControl” bool).
