File Display pane can't pin the pinned item to the top in time

In the directory below, I have three folders set status to pinned, they are:

  • Camera
  • ScreenShots
  • 迷你相册

I've set their color to green to discern

But, when I enter this current folder ( Details + Thumbnails mode), the DO won't pin all the three folder to the top, because the later two item is out of the scope initially:

Only after I scroll down to show the rest items, then, all the three are pinned to the top:

I wonder if this is not intended and can be fixed?
