Shaving the 2pts from the tabstrip now brings it in line with the MD spec, but I think we need to revert this change. If your tabstrip is filled with tabs, there no longer any space above the tabs to drag the window. When I try I get the window resize cursor. I have to grab the window near the stoplight or account login buttons in order to move it.

That's a good point. I'm able to move the window, but I have to carefully select the space above the tabs in order to do it.

spqchan@ - please go ahead and revert this change (so that we can get it into tomorrow's Canary). Thank you.
