React on drag-down gesture and prevent reload

Intro: When visiting a website on a mobile device and the website is already scrolled to top, then you can drag the page further down (as with many apps) into “negative” space to reload the page.

Now in my case, I have a web app that looks and behaves like an app. So I see that sometimes people use this drag gesture in order to close an overlay. However, the website gets reloaded instead – since this is the browser default behaviour.

Can I somehow prevent the page reload and/or react on that specific gesture?
