Type error in hover event

[TheLogan]

There seems to be an error in the type definition. I have the following code which works as expected, but I need the ts-ignore to have it not freak out, but apart from that the code runs as expected.

onHover={event => {
    // @ts-ignore
    event.event.target.style.cursor = 'pointer'
}}

onUnhover={event => {
    // @ts-ignore
    event.event.target.style.cursor = 'auto'
}}
