For me that behavior is "normal" in the sense that I see it happen here
all the time, when editing C files, on the average once in a minute.
But since it never disrupts my typing I simply got used to it.

What's bothering me more is that when I put an overlay somewhere in a
buffer and eventually remove it, underlying text properties provided by
the font locking mechanism are never restored unless I explicitly edit
the line where such properties should be seen.  Apparently so, because
font locking does not trigger when overlays get removed because that
does not count as a buffer change.  Another thing I got used to ...
