"All" view not selected for all relevant views for custom post type

[alpipego]

When the screen options get saved, the parameter mode=list gets appended to the URL. For the posts table, the “All” view gets the .current HTML class, since \WP_Posts_List_Table::is_base_request() returns true. For all other post types—including pages—it returns false.

Analogous to the paged parameter, unset mode whet checking whether
this is the base request for the \WP_Posts_List_Table.

We noticed the same happens for order and orderby—even for the posts table. I have updated the patch to consider order and orderby as well.

Per notes in the test report above:

This may benefit from additional testing for plugins that extend the WP_Posts_List_Table class. Adding needs-testing until this is done.
