The current behaviour of the 'Return to previous' report button in VA is to reload the report, not return to it. This is especially an issue if the initial report you have linked from has filters you have applied. When you select the button to return to the initial report, the filters are removed (or returned to the state as per the saved version of that report).
There would be a performance gain by returning to the report instead of reloading it, especially if the initial rpeort is complex with many objects/tabs.
