The window is borderless. It's difficult to see what's going on with the original test file so I added a new one to the JBS. MaximizedBorderStage adds a thin red border to the edge of the scene so you can verify that the JavaFX window doesn't go under the toolbar, the top edge of the window is flush with the bottom edge of the toolbar.

When I run these two test programs using the current JavaFX master they both fail (the windows don't iconify or maximize) but they work correctly with this fix. This is on my Mac running 13.6 but the OS version shouldn't matter.
