Comments inside type signatures break formatting

[Smaug123]

Issue created from fantomas-ui

The original code is valid; the transformed code is not, due to the indentation on the int.

Code

module Bar =
  let f a
    // foo
    : int
    =
    0

Error

module Bar =
    let f a:
    // foo
    int =
        0
