Change title font size in Plotly-CodePudding

I'm trying to update the title font size on my plot using the Plotly library, but it doesn't works. This is how I defined my layout:

y_layout = {
        'title': 'y / y_hat comparison',
        'shapes': y_shapes,
        'title_font_size': 6,
    }
y_df.iplot(kind='scatter', layout=y_layout)

It correctly set the the title and the shapes, but not the font size.

I think you can set the title font size using a dictionary:

y_layout = {
        'title': 'y / y_hat comparison',
        'shapes': y_shapes,
        'font': {'size': 6},
    }
