Expected behaviour

Chrome should scroll the usual amount.

Actual behaviour

Chrome scrolls roughly the same amount Firefox was scrolled while Firefox was active!

Steps to reproduce the behaviour

Preparations: Open Firefox and Chrome windows in maximized state and switch between the windows using alt-tab while the mouse cursor is above the content area. Load a long web page to both browsers and scroll near the middle of document in both Firefox and Chrome.

  1. Switch to Chrome using alt-tab.
  2. Scroll downwards with a couple of clicks on mouse wheel.
  3. Keep mouse cursor above the browser content area and press Alt+tab to switch to Firefox.
  4. Scroll downwards a lot using mouse wheel.
  5. Switch back to Chrome using alt+tab
  6. Scroll downwards one click using mouse wheel.

For some reason two instances of Firefox (Chrome not installed here) don't do this
