Reproduce the issue through the webchat-loader URL using the listed 4.18.1-main version, mockBot, White Label experience, and the Proactive search result at 320px reflow. Inspect the rendered proactive code content in Edge with Windows Narrator; done means the full content remains visible without truncation at that viewport.
