has_wpjm_shortcode array_intersect discards passed shortcodes (unless added via another filter)

https://github.com/Automattic/WP-Job-Manager/blob/c5c57804536423b11508202a79faa5c17fab5287/wp-job-manager-functions.php#L788

Why is `array_intersect` being used here? I understand that `job_manager_shortcodes` can be used to add shortcodes, but doesn't this kind of defeat the purpose of allowing shortcodes to be passed in `$tag` argument? This basically causes any passed shortcodes in `$tag` to be discarded if they are not also added via `job_manager_shortcodes` filter.

I understand this would allow you to check for a specific shortcode, but ONLY ones that exist in `job_manager_shortcodes` as well ... and since Resume Manager does not add any of the shortcodes using `job_manager_shortcodes` filter ... it will return false, even if you pass `submit_resume_form` to `has_wpjm_shortcode`

Is this the intended functionality for `has_wpjm_shortcode`?

Start in wp-job-manager-functions.php around line 788 and read has_wpjm_shortcode, focusing on how the passed $tag argument is combined with the job_manager_shortcodes filter. Reproduce the submit_resume_form case described in the issue and check existing tests or shortcode handling nearby. Done means the intended behavior for passed shortcodes is established and covered by a regression test.
