Duplicate ///-comments when immediately preceded by a //-comment

Issue created from fantomas-online

Code

// Maybe computation expression builder, copied from ExtCore library
/// https://github.com/jack-pappas/ExtCore/blob/master/ExtCore/Control.fs
[<Sealed>]
type MaybeBuilder() = class end

Result

// Maybe computation expression builder, copied from ExtCore library
/// https://github.com/jack-pappas/ExtCore/blob/master/ExtCore/Control.fs
/// https://github.com/jack-pappas/ExtCore/blob/master/ExtCore/Control.fs
/// https://github.com/jack-pappas/ExtCore/blob/master/ExtCore/Control.fs
/// https://github.com/jack-pappas/ExtCore/blob/master/ExtCore/Control.fs
[<Sealed>]
type MaybeBuilder() =
    class
    end

Problem description

Something's causing the ///-comment for the type here to be replicated. In the actual source (FSAC), this comment line was duplicated ~150 times.

It can be worked around by making the //-comment line a ///-comment line instead, which preserves the correct behavior.

Extra information

• The formatted result breaks by code.
• The formatted result gives compiler warnings.
• I or my company would be willing to help fix this.

_{Did you know that you can ignore files when formatting from fantomas-tool or the FAKE targets by using a .fantomasignore file?}
