This behavior seems as not related to extensions infrastructure:

postgres=#  CREATE TEMPORARY TABLE temp (id int);
CREATE TABLE
postgres=# set search_path to 'pg_temp_3';
SET
postgres=# create function foo() returns int as 'select 1' language sql;
CREATE FUNCTION
postgres=# select pg_temp_3.foo();
 foo 
-----
   1
(1 row)

postgres=# select foo();
ERROR:  function foo() does not exist
LINE 1: select foo();
               ^
HINT:  No function matches the given name and argument types. You might need to add explicit type casts.
postgres=# show search_path ;
 search_path 
-------------
 pg_temp_3
(1 row)
