This does not happen in Firefox. Reproducible: Always Steps to Reproduce: 1. Open a page with form elements, and/or a scrollbar, or Preferences 2. Click on another app Actual Results: Form elements and scrollbar retain their blue/graphite accents Expected Results: They should become white/light gray. This sounds like a pretty minor bug, but you can really get used to these things helping to indicate focus. Every so often lately I'd been meaning to type something into Firefox but it went to another app, and I just realized this is probably why.
