$.extend() with one parameter will merge the given options into the
global `jQuery` object, which was definitely not intended here. Maybe
the `config` variable was supposed to be passed as the second
parameter, but it doesn't look like that would do anything either.
Accessing the global `jQuery` object in that way ended up generating
completely unrelated warnings about deprecated `$.trimByteLength`,
which was reported in the task.
Follow-up to 7658e151d6.
