/**
 * SkipObjectsModal wiring: the request it sends when objects are skipped.
 *
 * The printer identifies objects by their slicer object id, not by their
 * position in the list, so picking the 1st and 3rd object must send their ids.
 * Already-skipped objects can't be picked again, and the submit button is gated
 * on printers:control and on the print being past layer 1.
