从问题解决的办法来看，貌似输入法的聚焦和组件的聚焦有关，而 mouseleave 之前直接一刀切的将 hover 事件移除，所以影响到输入法的聚焦了，从而导致这个问题。这样理解是否正确？ @Volankey @07akioni

@Volankey 这和之前的 form item 的一个 bug 有关，关联一下看看对不对

可以这么理解，但是并不在的为啥 mouseleave 会触发 compositionEnd`

对，就是找的 #905 的问题，发现最终是 clearable 的 input 组件都有这个问题

合一下pr @07akioni

我发现这个 hoverRef.value 会影响 showClearButton，这不是正确的改法，想要避免 rerender 需要 useMemo
