Invisibility Separation

With spells such as Veil of Invisibility, what happens to items they release from their person? Be it loosing an arrow, bleeding on the floor, putting down an item, etc.

Personally, I've always ruled that such items immediately reappear when they stop touching the target of the invisibility spell.

Conversely, when the target picks up a small object that they can easily carry, that object disappears.
