How to remove the return to the original position of the page from the iframe in your mobile application on IOS (Ipone)?

Question

HTML

Hello. I am building my Ionic app. The essence of the application is simple: display the page of the site. I do it through an iframe, the code looks like this:

<ion-content>
  <iframe src="https://pizzagusto.ru/sales/" width="100%" height="100%" frameborder = "no" scrolling="yes">
    Данный текст будет показан, если браузер
    не поддерживает фреймы.
  </iframe>
</ion-content>

When I run this application on Iphone and try to scroll down the page, the subsequent elements of the page are loaded as a result of which I return to the original position (top of the page). Moreover, there is no such problem on the computer, that is, scrolling works fine. How to avoid it?
