This avoids big restyles when users have a massive number of tabs. A color change inherits, so we need to propagate the color change to the whole subtree, which with a lot of tabs can be huge (66k elements in the profile in the bug). Instead, don't change the text color on inactive windows, and fade the titlebar entirely using opacity, which is a one-element change.
