Scroll index of full screen photos is never reseted

[FortyDays-k]

Let say I have three photos in my gallery identified as A, B and C

• I touch the photo A, it open in full screen, then I scroll until I reach photo C
• I close the full screen photos (either with the close button or the navigate back system button)
• I touch the photo A again, the photo C open in full screen instead

After closing the full screen view the scroll index should be dropped and opening the same photo should display it instead of displaying the last "scrolled to photo"

Additional test for the fun : If I scroll back to photo B, close, and reopen photo A, I got the photo B in full screen.
