Show all suppliers in filter dropdown

[loeffe1]

Why are suppliers limited to 100 in the filter by

$items = $cntl->compare( '==', 'supplier.id', $view->param( 'f_supid', [] ) )
->slice( 0, 100 )->search()->replace( $items );

and is there any way to remove that limitation other than settings slice to a higher value in a custom class?

In a perfect setup, only suppliers that actually have products within the current category should be shown, is there any way to achieve this?

It has been limited in the past to limit the data that's loaded and rendered in the page so avoid slow page loads.
Since 2022.10+, suppliers are loaded dynamically using a combobox and retrieving the suppliers via JS.
