Bulk action filtering was introduced in 3.1, but only to remove default bulk actions, not add new ones.
Bulk actions can now be registered for all admin list table dropdowns via the `bulk_actions-{get_current_screen()->id}` filter. Handling custom bulk actions can be performed in the corresponding and newly introduced `handle_bulk_actions-${get_current_screen()->id}` filter.
Props scribu, flixos90, Veraxus.
See #16031.
