Howa: Having multiple documents open inside the browser is not the same as having multiple Applications running. Android closes applications down when it runs out of memory. But having a second 'tab' open is not part of this. Having multiple tabs open is your responsibility, not the system's! So the system couldn't prevent it if you forget you left the page open. You opened a second page yourself instead of using the same 'tab' to open up a new site. If you would have done that, then finance gone and wouldn't have been refreshing.
