frame 1
previous folder with content
frame 2
new folder selected, column without content (white flash)
frame 3
new folder selected, with content and large column size
frame 4
new folder selected, with content and resized column
Ideally, the transition should go from frame 1 to frame 4 directly. At high speed, frame 3 makes it look like the folder contents are “flashing” because it transitions to white before updating.
