Touch events unresponsive for flexible child Views in ScrollView component under React Native new architecture

yandadaFreedom commented 2 days ago

Description

There is an issue with the touch events in a ScrollView when using the new architecture. Specifically, below a ScrollView, there is a View component with a minWidth of 100%. Inside this View, there are three child View components, each set with flexGrow: 1, flexShrink: 1, and flexBasis: "25%". The last two child View component does not respond to the touchstart event under the new architecture, while it works fine in the old architecture.

Steps to reproduce

Create a ScrollView component provided by react-native and set horizontal to true
Place a View component below the ScrollView with minWidth: 100%.
Inside the View component, add three child View components, each with flexGrow: 1, flexShrink: 1, and flexBasis: "25%".
Test the touchstart event on the last two child View component.

Expected Result: The last two child View components should respond to the touchstart event.

Actual Result: The last two child View components do not respond to the touchstart event when using the new architecture, while this issue does not occur in the old architecture.
