KeepIfThenInSameLine breaks function indentation

[Smaug123]

Issue created from fantomas-online

Code

let foo () =
    blah
    |> function
        | x -> ()

Result

let foo () =
    blah
    |> function
    | x -> ()

Problem description

The match here needs to be indented one place to avoid an offside error.

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?}

KeepIfThenInSameLine is actually unrelated here, the problem is more centered around the combo infix operation and SynExpr.MatchLambda.
