SimpleChatTCRV:UICleanup:Popover Firefox work around

As firefox doesnt seem to currently support anchor based relative
positioning of the popover, so explicitly set the position of the
popover.

Also reposition the popover to be in the bottom right corner rather
than the previous top center position.
* Rather updated position-area css property ensures this automatically
  wrt chrome browsers.
* while for firefox the explicit code that is added is needed.

NOTE: Had added that id, just in case firefox was goofing up bcas of
the element not having unique id or so, either way the firefox issue
is unrelated and more fundamental lack of support for now.
