Failed to construct 'ResizeObserver': Please use the 'new' operator, this DOM object constructor cannot be called as a function. TypeError: Failed to construct 'ResizeObserver': Please use the 'new' operator, this DOM object constructor cannot be called as a function.

这个错误通常是因为在调用 ResizeObserver 构造函数时没有使用 `new` 运算符。正确的用法是使用 `new` 运算符创建 ResizeObserver 实例，例如：

const observer = new ResizeObserver(callback);

请确保在调用 ResizeObserver 构造函数时添加 `new` 运算符，并将回调函数作为参数传递给它。这样就可以成功创建 ResizeObserver 实例了。
