    // button is not nested inside another element because when user changes colours in Firefox,
    // the immediate background colour of buttons is always white (again, regardless of user's
    // custom colours).

    // sets a background colour, the text colour is still black but the background of that nested
    // element gets the user's custom background colour. When the custom background is a lighter
    // hue, the contrast might be sufficient. But if the user's custom background colour is a
    // darker colour, the contrast with the text might not be sufficient.
    //
    // To ensure sufficient contrast, override the background colour set by the focus state on the
    // nested elements to be transparent.

    // Also override the background colour of the Show/Hide chevrons which set a background colour
    // on hover.
