search form in edit.php should keep parameters it does not understand

[ibotty]

the component is class-wp-list-table.php.

if you carry along some kind of status in the url in the post list (e.g. url=​https://example.com/wp-admin/edit.php?post_type=post&my_status="abcdefg") the search field should not remove the parameter.

The search form simply posts back a form. Anything that isn't a form input won't get submitted.

yes. that is clear.

but instead of returning to the original url (with some parameters in it), afair it returns to a url w/o these parameters.

hope, that clears things up.
