Type error in hover event

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'
}}

該 issue 只提供了 onHover 和 onUnhover 程式碼片段，沒有指明檔案或測試。先定位這些事件處理器的型別定義，並檢查為什麼 event.event.target 需要 ts-ignore；當程式碼片段不使用這些忽略指令即可通過型別檢查，且現有行為維持不變時，即視為完成。
