Generally yes. The vanishingly small oval might be a
legal exception, since it is only outlined, not filled.
(a filled oval *is* found by its coords)

Depending on the item type there may be documented
exceptions (points that are defined to be *not* part of
the item), that can lead to unexpected effects on very
small items.

For your problem: just use a filled oval, and it should
work as you intended.
