MSDocRenderer keep reloading the file when scrolling on mobile web browser

I am using the following code to render MsDoc file on my web page:

` `

It works on Desktop.

But when I test it on mobile web browser, As long as I scroll my screen, the iframe would reload the file, making it unusable.

Also when on Desktop, if I change my browser screen width, it will also causing the iframe to reload.

Here is a video showing what I see: https://www.youtube.com/shorts/K_n4Xr_EFEE

Anyone knows what might be wrong here?

Start by reproducing issue 239 with DocViewer and MSDocRenderer on a mobile browser, then compare behavior while scrolling and resizing the desktop viewport. Trace the renderer and iframe lifecycle to identify the reload trigger; done means the document remains usable without reloading during scrolling or resizing.
