Arpeggio across notes of differing lengths

[Joel C. Salomon]

In the score to Peter Pan I’ve come across what appears to be an
arpeggio with notes of different lengths.  I’ve come up with the kluge
below, but it doesn’t really look right (the hidden notes take up space,
and show up in the MIDI output).  What’s the correct way to achieve this?

    \version "2.19.44"
    \language "english"

    lower = \relative c {
        \clef bass
        \key d \minor
        \time 2/4
    <<  {
            \voiceOne
            bf'2                |
        }
        \new Voice {
            \voiceTwo
            f,4        e        |
        }
        \new Voice {
            \voiceTwo
            \hideNotes
            \arpeggioParenthesis
            <f bf'>4\arpeggio
            \arpeggioNormal
            \unHideNotes
        }
    >>
        \oneVoice
    }

    \score {
        \new Staff = "lower" \lower
        \layout {}
    }
