Polar plot title and axes have odd text-shadow that cannot be changed?

[djkashtan]

If you look at the css or just simply mouse-highlight the title or axes on a polar plot, the text has a white text-shadow. I could not find an option to change it. The legend does not have a text shadow and other plot titles and axes do not appear to have text-shadows by default. Can anybody help me? My website does not have a white background and my polar plot looks really ugly with the white text-shadow.

This link has polar plots that demonstrate the behavior: https://plot.ly/javascript/polar-chart/

From v1.0.0 release notes:

Polar charts are under-developed.

This is already available in the layout object of the polar plot.

layout: {
    font: {
        outlineColor: 'transparent'  // or repeat layout.paper_bgcolor here
    }
    //...
}
