VictoryAxis events not firing correctly on grid target

[amaschas]

Given a VictoryAxis configured like this:

<VictoryAxis
  events={[{
    target: 'grid',
    eventHandlers: {
      onMouseOver: () => {
        console.log('test');
      }
    }
  }]}
/>

The event handler never fires on mouse over. I've also tried with onClick. The onMouseOver event fires if the target is tick, but the onClick event doesn't seem to. According to the docs, this should work.
