It is a bug in the sense that it is contrary to the expectations of
anyone using the cursor-type variable.  That is, even if you think the
code is doing what you intended it to do, I think the intended
behavior is wrong.

I don't understand this, because when the cursor blinks off for me, it
disappears completely.

There are several situations which can now result in distinct cursor
appearances:

  the window is selected

  the window is selected, the cursor is "blinking", and it has blinked
  "off"

  the window is not selected

There are also variations in the shape of the cursor (bar of various
thicknesses, block, hollow block, completely missing) and the color of
the cursor.

It seems to me that the shape and color of the cursor should be
selectable for each situation.  So you could make the cursor "blink"
by changing color or thickness instead of disappearing.
