Additional context
Sample canvas in copilot studio

Start with CopilotStudioSamples/BuildYourOwnCanvasSamples and the generated HTML file using the Web Chat CDN. Reproduce the behavior in the browser and compare the responses with the same bot in Copilot Studio. Done means the embedded Web Chat provides the expected answers; the issue needs more complete reproduction steps to identify the relevant change.
