 This is a follow-up to #32499.

 In the function get_hidden_columns() the simple test to see if the user
 has hidden columns or not is
 if ( ! $hidden ) {
 however that also happens when the user has chosen to show all columns,
 it's and empty array.
 better would be
 if ( $hidden === false ) {
 that way the default_hidden_columns filter will only fire if the user
 option does not exist at all.
