When dragging very narrow tabs in a tabstrip, the tab drag hysteresis, where there's some slop before each tab snaps into a new position on the opposite side of the dragged group, works differently for dragging one versus several tabs.  The multi-tab case feels like it's off by some fixed amount in one direction.

This could have something to do with how TabDragController::GetDraggedViewTabStripBounds() only looks at one attached tab instead of all dragged tabs.  Or not, I'm not sure.

This becomes egregious in refresh with very narrow tabs.
