Android ChatGPT App: scrollable containers inside Apps SDK widgets do not receive vertical scroll gestures

I am seeing a potential issue in the ChatGPT Android app when using Apps SDK widgets. Environment: * ChatGPT Android app * Apps SDK widget * React + Tailwind * Widget rendered inside iframe Minimal reproduction: Test 1: * Widget with a fixed-height container * Inner content uses overflow-y-scroll * Multiple items to force scrolling Result: * Widget renders correctly * Vertical swipe gestures do not scroll the inner container * Content appears static Test 2: * Same widget * Removed overflow-y-scroll * Content grows naturally and scrolling is handled by the ChatGPT conversation Result: * Scrolling works correctly * All content is accessible We also tested: * notifyIntrinsicHeight() * maxHeight / safeArea * min-h-0 / flex layout adjustments * overscroll-behavior variations * touch-action variations None changed the behavior. Question: Are nested scrollable containers officially supported inside Apps SDK widgets on Android? Has anyone else experienced issues with overflow-y-scroll regions inside Apps SDK widgets in the ChatGPT Android client?
