      Yes. This must be it. I've observed something else that may help in locating
      the problem: dragging the status line generally causes the cursor to be
      moved to the window just above the status line, regardless of where it was
      originally. When the window containing the cursor after the resize has the
      same syntax as the window whose highlighting is in question, the
      highlighting remains correct; only when the window directly above the status
      line corresponds to a different syntax does the problem occur.
