ScrollView resetting scroll offset after being offloaded and reloaded onto the view

Vega Open Beta Bug Reports
1

1. Summary

After updating the SDK to version 0.22.6150 we noticed that ScrollViews reset their scroll offset once another navigation stack is placed over it. This occurs most of the time but not always.

It also affects ScrollViews that have been hidden with `display: none` and then re-added to the view.

This applies to all Scrollviews, horizontal and vertical.

Hi @Hossam_Elnadi,

We attempted to reproduce the ScrollView scroll offset reset behavior on our test device, but weren’t able to observe the problem you described.

Could you please provide logs from when the issue occurs? This will help us investigate what might be causing the behavior in your specific scenario.

Thanks,
Aishwarya
