Plot curves disappear when using latex formatted axes titles

I’m trying to plot some basic curves in a scatter plot, using the offline plotting features. The plots work fine with regular text labels, but when I add LaTeX labels all the curves disappear.

    layout = go.Layout(
        xaxis=dict(
            title='Time (hours)'
        ),
        yaxis=dict(
            title='$OD_{600}$'
        )
    )
    fig = go.Figure(data=trace, layout=layout)
    plot(fig)

vs

    layout = go.Layout(
        xaxis=dict(
            title='Time (hours)'
        ),
        yaxis=dict(
            title='OD600'
        )
    )
    fig = go.Figure(data=trace, layout=layout)
    plot(fig)

Any ideas?
