Task logs page doesn't respect result filter when moving through the pagination

Run moodle cron several times to generate some task logs (e.g. from command line php admin/cli/cron.php) Navigate to Site administration > Server Tasks > Task logs If not enough records for pagination, then update number per page to 1 or 2 in https://github.com/moodle/moodle/blob/master/admin/tasklogs.php#L92  so it is like $table->out(2, false); Change Result filter to Success and click Filter button. Navigate through pages and confirm that Result filter is staying set to Success .
