Andrea's idea of "recycling" elements instead of replacing is very
interesting: I'm going to carefully look at all the examples in your wiki
page, and see if this could always be done or just in some lucky cases.
Anyway: not all the elements after the break are made "invalid", but just
the ones referring to the same row group, so they would not be many.
