Is it common for books written in English to have an American edition
and a British edition in which there are differences in text besides
the idiosyncrasies in spelling?

Yes.
Anthony Burgess has written bitterly about the
readiness of US publishers to change the content
of books published elsewhere. Burgess complains
the US publisher of A Clockwork Orange suppressed
a whole chapter of the English book (without telling
the author?)

Canadian authors often complained 1950-80 that
US publishers told them to revise books about ordinary
rural or urban life in contemporary Canada so that
they purported to be about US cities and places.
Before 1950 it seems the (few) Canadian authors
complied, as the price of publication: and more
recently US publishers may have found it unnecessary.
