Chatbot does not display Welcome Message in WebPage on 1st load



A web Chatbot is configured in Pega 8.3.

The Mashup code of the web Chatbot is embedded in an HTML page which is deployed in an Apache Tomcat server (\webapps\Chatbot\index.html) for testing. 
On using the URL in a browser, the Pega Chatbot loads without a Welcome message. However, on reloading the current page, the Welcome message displays in the Console.
