Marker with opacity by value, but constant line (marker edge) opactipy

Iā€™m trying to plat marker where maker opacity is changed by some vector.
But marker edge color opacity is constant.

   fig.add_trace(go.Scatter(x=real.index, y=real['some_value'],
                             marker={'opacity': real['another value'],

It can be shown in plot below, that the marker edge color opacity, is changed together with color opacity.
My purpose to keep line (marker edge ) opacity constant.
