Issue Details
WebView does not scroll when placed inside a ScrollView. The parent ScrollView intercepts vertical touch gestures, preventing the WebView from scrolling its internal content.
Root Cause
The parent ScrollView was intercepting all touch events without checking if the child WebView needed to scroll. This prevented the WebView from receiving touch events and handling its own scrolling.
Description of Change
Added touch event handling to prevent parent interception when WebView scrolls. When touch begins or continues, WebView requests exclusive control from parent. When touch ends or cancels, control returns to parent. This enables WebView scrolling while preserving normal parent-child interaction.
Validated the behavior in the following platforms
