Description
Currently only the normal (i. e. unhighlighted) background color can be changed through the parameter bgcolor. If you set this background to a dark coloring, you most probaby also want to adjust the text font to a bright coloring so that the text is still readable. But then the text becomes pretty unreadable while being highlighted since the highlighting background color is very bright!
Therefore I think an additional parameter bgcolor_active or the like should be introduced.
Additionally, an even more sophisticated solution could involve an automatic adjustment of the text font color and/or background color depending on the color brightness of the user defined bgcolor and/or font.color values (this seems to be already the case with the font color of hoverinfo labels).

Research direction
Start with the layout updatemenus reference entries for bgcolor and font.color, then trace the existing highlighted-state handling. Decide whether the requested active background option is the scoped change; done means the option is documented and highlighted controls remain readable with dark normal backgrounds, with coverage for the new behavior.
