I agree fully with your description of the problem. I cannot think of a good
solution, besides ignoring it. In the case of extensions, this might cost one
ply now and then, when you see a tactical problem later. Related is the problem
with repetitions (and 50 moves rule), which are also not handled correctly by
the HT.
