If I understand these paragraphs right, the first one seems to say that the cursor does not appear, and the second one says the cursor will not appear unless the programmer has used the :heuristic-mask property. Did I understand them right? If that is true, we have a bug, right? But the third paragraph seems to say that the default for :heuristic-mask is such as to make sure the cursor appears. Did I understand that right? If that is true, then maybe we don't have a bug. What's the real situation here?
