Describe the bug
When adding any x options to the <Plot />, an empty title prop on the <XAxis /> doesn’t empty the title.

To Reproduce

This still shows an automatically generated title for the x axis, which I explicitly did not want.

 <Plot marginBottom={80} y={{grid: true}} x={{insetLeft: 20}}>
    <AxisX title={''} tickFormat={(d) => `${d}%`} tickSize={0} />

Expected behavior
Should not show a title

Additional context

This fixes it

<Plot marginBottom={80} y={{grid: true}} x={{insetLeft: 20, label: false}}>
    <AxisX title={''} tickFormat={(d) => `${d}%`} tickSize={0} />
