fix #13813 : Dark Mode: The ForeColor & BackColor properties are not working for the controls

[Epica3055]

Fixes #13813

Proposed changes

Add code to see if BackColor or ForeColor is specified in dark mode, if so then use the specified color, if not then let the renderer decide the color.

It's the right approach, if we wanted the set color to change the renderer.
But I think, we should not do it.

We should only take ForeColor and BackColor in DarkMode into account, if the Flat- or the Popup renderer is activated.

And then the question is: Could we "just" figure out, if Back/ForeColor should be serialized with the current setting, and if, only then take that color then into account for the Back and ForeColor renderer?

Hey @Epica,

could you see why the test fails and then squash the commits and rebase?
Ping me, if you want me to explain in more detail, what I mean exactly. :-)

Thanks for your help!
