Describe the problem

When the OS theme is dark and the IDE theme is dark, the plotter app's default background should be dark too. Now it has the default white background color.

To reproduce

• Set the IDE2 theme to dark (or when it's dark by default IDE startup theme based on OS theme #1160 ),
• Start the monitor,
• Tools > Serial Plotter,
• The plotter loads with a white background color.
