Motivation

If the tooltip got rendered in an FlatList an Tooltip render error could occur when running in an simulator with hermes.

Invariant Violation: [9217,"RCTView",11,{"position":"absolute","top":"<>","backgroundColor":0,"overflow":"visible"}] is not usable as a native method argument

Setting the default values fixed this.
Also described here already from another user:
