Problem

highlighter.removeAll()API不起作用。追踪了代码，发现util/dom.ts 42 行getHighlightsByRoot()函数中没有返回concat后的新值。

export const getHighlightsByRoot = ($roots: HTMLElement | Array<HTMLElement>): Array<HTMLElement> => {
    if (!Array.isArray($roots)) {
        $roots = [$roots];
    }

    const $wraps = [];
    for (let i = 0; i < $roots.length; i++) {
        const $list = $roots[i].querySelectorAll(`${WRAP_TAG}[data-${DATASET_IDENTIFIER}]`);
        // $wraps.concat($list);
        $wraps.push.apply($wraps, $list);
    }
    return $wraps;
}
