Switch expression single line broken when preceded by comment

[charliefoxtwo]

Version 0.28.2

Input:

public class ClassName {
    private static void Foo(Bar bar)
    {
        var y = bar switch
        {
            // comment
            Bar.A => 1,
            Bar.B => 2,
        };

        var z = bar switch
        {
            Bar.A => 1,
             // comment
            Bar.B => 2,
        };
    }

    enum Bar
    {
        A,
        B,
    }
}

Output:

public class ClassName
{
    private static void Foo(Bar bar)
    {
        var y = bar switch
        {
            // comment
            Bar.A
                => 1,
            Bar.B => 2,
        };

        var z = bar switch
        {
            Bar.A => 1,
            // comment
            Bar.B
                => 2,
        };
    }

    enum Bar
    {
        A,
        B,
    }
}

Expected behavior:
input should not be changed, and switch cases preceded by a comment should not be broken into separate lines.
