The odd behaviour is probably because it is a chooser with simple_values=True. In that case the combobox behavesvery differently and does not provide pagination because that would be difficult to implement when the data is not in a database. Such choosers usually show a reasonable number of rows. Note that filtering works (users just need to know…).

I suggest to add a full_clean() method to lino.modlib.users.mixins.TimezoneHolder which protects us from having invalid values.
