    Issue #8670: the color of the "selected text" field seems too dark.
    
    Just use an inverted logic for the selected text (i.e. white on black in light
    mode, or black on white in dark mode). This is the usual logic for rendering
    selected text anyway (except that we don't use non-grayscale colors, e.g. blue
    background is common in system themes).
