VS Code | Extra white space added to record definition

[lqdev]

Issue created from fantomas-online

Please describe here fantomas problem you encountered

Using VS Code with editor.formatOnSave set to true, given code like the one below on an fsx file, an extra line is always added to the first record type definition (in this case Commenter). Each time the fsx file is saved, a new line is added. It only happens on the first record type definition though. All other records are not affected.

Code

type Commenter =
    { [<JsonProperty("display_name")>]
      DisplayName: string }

type Message =
    { [<JsonProperty("body")>]
      Body: string }

Result

type Commenter =
    { [<JsonProperty("display_name")>]

      DisplayName: string }

type Message =
    { [<JsonProperty("body")>]
      Body: string }
