To prevent the flicker happening, the animation is being applied to both progress bar and storage size info in the storage item. Bug: 222421324 Test: manual test 1) Install memory fill 2) Increase storage size using memory fill 3) Navigate to Settings > Storage 3) Check the progress bar and size info has animation when updating Change-Id: I4583358697afd416bc20cafac3ff89361397b6b9
