This isn't a bug, because those are not the same word. If you looked
closer, you'd find:

regression=# SELECT to_tsvector('surprise') , to_tsquery('surpris');
to_tsvector | to_tsquery
-------------+------------
'surpris':1 | 'surpri'
(1 row)

If you want to put in already-stemmed words, don't feed them through
to_tsquery, just cast directly to tsquery:

regression=# SELECT to_tsvector('surprise') @@ 'surpris'::tsquery;
?column?
----------
t
(1 row)
