How to prevent refresh on overscroll on IOS

Hi, I have this small problem - refresh on scroll. So i have box inside my application with drag and drop feature. It works everywhere besides phones.

can you show us the code for drag and drop (the event listeners). Thinking of it, I don't know if mobile supports drag-events. Think you need seperate touchmove and touchend events for that

ohw, here a nice video of Web Dev Simplified on touch events. He also mentions the page refresh. https://www.youtube.com/watch?v=TaPdgj8mucI

try putting in your events as the first line event.preventDefault()

put in onto pointerMove and didn't change anything

hm, i have no knowledge about the onDown and OnMove events of react. Don't know if they only capture clickevents or also touch. i can not test it, but will this work?

onDown = (event) => {
    event.preventDefault(); // THIS ADDED
    this.isDragging = true;
    event.target.setPointerCapture(event.pointerId);

    // We store the initial coordinates to be able to calculate the changes
    // later on.
    this.extractPositionDelta(event);
  };

onDown = (event) => {
    event.preventDefault(); // THIS ADDED
    this.isDragging = true;
    event.target.setPointerCapture(event.pointerId);

    // We store the initial coordinates to be able to calculate the changes
    // later on.
    this.extractPositionDelta(event);
  };

i added the event.preventDefault(). You probably can put that line in the other onMove, onUp, onGotCapture and onLostCapture as well

The problem behaviour looks like this - Slide is absolute div with 85vh and bottom:0 - Behide Slide there is rest of aplication so it is this typical overlay with 85vh - when i drag the slider stays in place but everything what is in the backgroud moves and enforces page reload so it seems that stop-propagation should work but it doesn't @markboots. do you think am I missing something?

I think overscroll-behavior could fix this? an overscroll-behavior: contain should prevent the page refresh?

This what i google, but seems it didn't worked maybe something weird is going on with this component because of position absolute, no idea to be honest wasn't able to find good solution for this
