new InfiniteViewer will empty the iframe

[zlyyyy]

There is an iframe in the viewport, and the content of the iframe will be cleared after the new InfiniteViewer

Here is my minimal rendition https://stackblitz.com/edit/stackblitz-starters-rb32s7?file=src%2FApp.tsx

@daybrush Trying to downgrade the version can't solve it, it seems to be a persistent problem

[zlyyyy]

It is normal to write before iframe write, and init will reproduce after write

[zlyyyy]

After looking at the source code, these two lines of code lead to

        if (!wrapperElement) {
            wrapperElement = doc.createElement("div");
            wrapperElement.insertBefore(this._viewportElement, null);
            containerElement.insertBefore(wrapperElement, null);
        }

If there is an iframe inside the viewport, refresh may occur during the process of appendChild and insertBefore. As in your comment, it's probably best to set the wrapperElement as an ad-hoc.

The framework also creates a wrapper and sets it through props.

@daybrush Yes, I temporarily solved it by setting wrapperElement
