There is a gap in Shell's Flyout as seen in the picture below:

(Header background is black and item background is yellow. The white in between is what I'm trying to remove.)
I have tested this in a blank new project (where I've also taken this screenshot) so I'm pretty sure it's not my code's doing. I tried setting margins and/or paddings to most of the elements in the AppShell.
If it helps, when I pull the items down, the blueish "you-are-trying-to-pull-a-scrollable-list-past-its-end" graphic is right below the header, so that makes me think that the gap is part of the Flyout's internal item list.
Any ideas on how I could remove the gap?
