When the personal dictionary is saved, ispell.el restarts Flyspell
mode, and that removes all the overlays used for highlighting.  This
code was a deliberate change to fix bug#11963, which see.  However,
since then, a better solution for the same scenario was already
installed, so this semi-kludgey fix is no longer needed.  I removed
that code now on the master branch, and that fixes this particular
bug.

Thanks.
