Fix the time range of all symbols to the Event Frame time range when selecting attributes from a specific Event Frame.

Customer Issue: When the customer drags Event Frame attributes onto a blank Coresight display and selects any symbol, the time range of the symbol is not fixed to the Event Frame time range. When the user moves the time bar at the bottom of the screen or lets the display update on its own, the values of the Event Frame symbol change with time.
