Thanks, I will have a look at this soon.  One thing I don't understand is
the influence of `global-display-line-numbers-mode` in all of this. I
suppose
the situation doesn't happen if it's off.  Knowing why will probably solve
the mystery.

Actually, having a look at the backtrace, it seems turning on
display-line-numbers-mode causes the tabulated list to reprint itself via
some
hook that is presumably there by default.

Anyway, this afternoon or tomorrow.
