Created attachment 8067 Image showing multiple rows with 50px panel height

When I increase the height of my panel to 50px and "Show button labels" is enabled, the "Window Buttons" panel item splits its buttons into multiple rows. Ideally, this should not happen unless I increase the "Number of rows" setting for the panel. See the top half of the attached image.

Also, the button icons seem to stop growing after a certain point. With "Show button labels" enabled, the icons seem to be the same size at 48px as they are at 28px height. With "Show button labels" disabled, the icons on the panel do not grow bigger after about 45-50px. You can set the panel to 100px tall and the icons will be the same size as they were when the panel is set to 50px tall. They seem to stop growing somewhere around 45px tall. See the attached image.
