我有一个自定义事件处理函数，如下所示

/** Dispatch event on click outside of node */
export function eventHandlers(node: HTMLElement) {
  
    const handleClick = (event: MouseEvent) => {
        if (node && !node.contains(event.target as Node)) {
            node.dispatchEvent(
                new CustomEvent('click_outside')
            )
            
        }
    };

    document.addEventListener('click', handleClick, true);
  
    return {
        destroy() {
            document.removeEventListener('click', handleClick, true);
        }
    }
}

当我试图在HTML中使用它时（svelte）如下，它抛出一个错误：
类型{ class: string; "on:click_outside": (event: MouseEvent) => void; }的实参不能赋值给类型Omit<Omit<HTMLLiAttributes, "pattern" | "style" | "title" | "cite" | "data" | "form" | "label" | "slot" | "span" | "summary" | "id" | "class" | "accesskey" | ...的形参300更多
html如下所示（svelte）

function handleClickOutside(event) {
        alert('Click outside!');
    }

<h1>Hello {name}!</h1>
<div use:clickOutside on:click_outside={handleClickOutside}>
    Click outside me!
</div>

这是什么意思，我该如何解决？
