// color partially transparent causes the selection color to mix with the text's
// regular background, so the end result will often have better contrast with
// the text than an arbitrary opaque selection color.
// The motivating example for this is the URL bar text field in the dark theme:
// White text on a light blue selection color has very bad contrast, whereas
// white text on dark blue (which what you get if you mix partially-transparent
// light blue with the black textbox background) has much better contrast.
