Comment dropped in constructor parameter list

[pbiggar]

Issue created from fantomas-online

Code

  type MyType
    (
      (* some comment *)
    ) = 
    let x = 5

Result

type MyType() =
    let x = 5

Problem description

The comment should not be dropped. This also happens if there are parameters present, but I reduced the test case to remove the parameters as it seems they're dropped regardless. Also happens with //-style comments.

Somewhere in CodePrinter we are not taking the parenthesis trivia into account.
Are you interested in submitting a PR?

Probably not for this one, it's a low-priority for me
