the theme now works in a way where the current tab is in one color with
the content, so its correctly assosiated. The not selected items are in
a bit more gray setting so its meant to be in the background.
I agree this makes the tabs visually stick to their pages, making them more obvious. However, there was a lot of effort put into the previous tab design so maybe we should ask the previous artist if he/she is OK with the change...
