show progress bar also when user left and re-entered the media tab screen

how to test:
1. click on file with big file size that was not clicked before (so it's not in the cache)
2. leave media tab view or just select other tab.
3. go back to the clicked file
4. --> see that progress bar is still spinning (otherwise it's already finished and a click should oen the file directly without showing the progress bar)
