<div onMouseOut={ () => void 0 } onBlur={ () => void 0 } />
<div onMouseOver={ () => void 0 } onFocus={ () => void 0 } {...otherProps} />

<div onMouseOver={ () => void 0 } />
<div onMouseOut={ () => void 0 } />
<div onMouseOver={ () => void 0 } {...otherProps} />
<div onMouseOut={ () => void 0 } {...otherProps} />
