Performance gets reduced even after navigating away from a page that contains animation. How do we handle this issue ?

The scenario is such that the animations in the page will continue to play until it is garbage collected, even when the page is navigated away to another page holding the memory and system resources for animation. There will be severe drop in performance when more animations are running in a page. To overcome this issue, ‘Unloaded’ event of the page can be used to remove the animations from the page such that the animations don’t consume memory and system resources.
