Describe the bug

When opening the calendar, it will not show the current month if the browser window height is above 1120px.

At a window height below 1120px it works as expected.

Will be fixed in the next version 👌

@chenjiahan 这个问题我看是代码中是初始化时只渲染上个月，当前月和下个月，因为Month是lazyRender，初始化时不能获取到month-body高度，所以请教下修改方向
months.forEach((month, index) => { month.visible = index >= visibleIndex - 1 && index <= visibleIndex + 1; });

In the current version, you can disable the lazy-render prop to avoid this problem

<van-calendar :lazy-render="false" />

In the next version, we will adjust the logic of lazy render to avoid this issue.

Fixed in version 2.10.10.
