File › Export Selection… collected the selected objects one asset per
object, so a few ungrouped shapes picked to export together came out as
separate images unless they were grouped first. It now collects them as one
asset of them all (`assets.add {multiple: false}`), the selection exported
as one image; `file.exportSelection {multiple: true}` still makes one per
object, and Object › Collect for Export › As Multiple Assets and the Asset
Export panel's Multiple Assets item are unchanged.
