Ah, somewhat weird. Firefox has that thick border, but other apps do not. Maybe something to do with GTK vs QT, not sure.
While the border is pretty much not there, it's still very easy to resize windows.
With the narrow border it's more obvious that indeed dragging area inside the window itself is smaller than outside it. Maybe to avoid overlapping with controls inside those windows?
Otherwise that scrollbar might be weirdly inaccessible.
