File manager can't resize vertically

Strangely I can't seem to resize even the most basic Window:

    egui::Window::new("test")
    .max_size([600.,600.])
    .resizable(true)
    .default_size([200.,200.])
    .show(ctx, |ui|{
        for i in 0..3 {
            ui.label("test");
        }
    });

If that's the case, this is likely a "generic" window issue and is the same thing affecting #581.

I just found this:
emilk/egui#465
It is a bit weird, but it seems to work by allocating space. Not sure how to make that work with our thumbnails though.
