"" -> `" does not work in functions

V1:

F1:: MsgBox % """" ; "
F2:: MsgBox % "abc""123" ; abc"123
F3:: MsgBox % "abc""123" MyFunc("", "123""abc") "" ; abc"123123"abc

MyFunc(a, b) {
  return a b
}

V2 (Converted):

F1::MsgBox("""") ; "
F2::MsgBox("abc""123") ; abc"123
F3::MsgBox("abc""123" MyFunc("", "123""abc") "") ; abc"123123"abc

MyFunc(a, b) {
  return a b
}

V2 (Expected):

F1::MsgBox("`"") ; "
F2::MsgBox("abc`"123") ; abc"123
F3::MsgBox("abc`"123" MyFunc("", "123`"abc") "") ; abc"123123"abc

MyFunc(a, b) {
  return a b
}

Ignore that all tests begin with F1::, issue is in MsgBox
