Just to clarify the question and answer:
The question is that why does the Tablet Application not refresh the EntityList if a User manually refreshes the browser.
This may be the expectation as this is the behavior in the Desktop Application.
It appears the answer is that: if a User wants a refresh of the EntityList, they should be doing that through the application’s controls (i.e. Search Toolbar) and NOT through the browser’s refresh (which may not be supported as it may be dependent on too many variables: browser type, device type etc).
