It seems, that this grey bar is visible for those tabs, which are in the 'view' of the Tabstrip. All other 'in the non-view area' of the Tabstrip has no grey bar.

Attached is a screenshot which demonstrates my comment 3:

3 tabs 'google.com' in the view (--> grey bar is visible)
3 tabs 'youtube.com' not in the view (--> no grey bar)

So... maybe a feature, but I don't know - looks strange.
