Looks like only the item slot is virtualised, and having extra elements mixed in breaks the height calculation:

vuetify/packages/vuetify/src/components/VDataTable/VDataTableVirtual.tsx

Lines 230 to 236 in e33b951

	...slots,
	item: itemSlotProps => (
	<VVirtualScrollItem
	key={ itemSlotProps.internalItem.index }
	renderless
	onUpdate:height={ height => handleItemResize(itemSlotProps.internalItem.index, height) }
	>
