In order to maintain session continuity between tabs, the tab that the chat originated from should remain open and cannot be used for navigation. If a visitor attempts to close out the tab, navigate to another page (on or off the same domain), or reloads the tab they will be prompted first by a browser warning:
"Leave site? Changes you made may not be saved."
Note: In Messaging for In-App and Web (MAIW), session persistence behavior differs and is managed by the SDK.
