      Yes, the patch makes the first typed character be mapped as if it was
      typed in Insert mode. That's consistent, the second character typed
      will be handled the same way.

      Visual mode mappings apply in Select mode as if it were Visual mode.
      Thus that's correct, even though it might not do what you want. I don't
      think this has anything to do with the patch though.

      I don't see a big disadvantage of this change, and it does make
      keymapping work for the first typed character in Select mode.
