Description Overview

<Item dataKey="key"/>

react/no-unknown-property: [2, requireDataLowercase: true}]

Raises false positive:

React does not recognize data-* props with uppercase characters on a DOM element. Found 'dataKey', use 'datakey' instead

Expected Behavior

No error because dataKey doesn't start with data-. The rule docs specifically mentions that it's only checking data-* attributes, e.g. with the -.
