 > Could you provide a demo, please?
 I added an attachment to the ticket. You need to enable Javascript.

 Changing the Windows theme (e.g. between Aero/Basic/Classic or some 3rd
 party theme) or customizing the scrollbar size changes the height values.

 You need to restart the browser for theme changes to take effect. Firefox
 only reads the theme at startup.
