Answer 1

TabControl uses a specialized TabPanel class and not a generic Panel like StackPanel because if you mess around with the TabControl you'll realize that the panel does quite a few things which generic panels dont. One is adjusting the tab header items in multiple rows. Another is that the the rows of items will be rearranged so that the selected tabitem header is always in the last row. I guess it might be doing even more

I am quite interested in knowing why putting the style in the window resource section does not work. My initial reaction was it should work until I tried it. I am adding this as an answer because SO wont let me add an image in a comment.
