Because the widest label on this tab is less wide than the widest label on the camera tab, the width of the tab/content is also less wide.
This results in a 'huge' gap between the tab/content and the right side of the window.
It is especially apparent when clicked back and forth between the camera and tracker tabs.
Adding some vertically_stretchable all over the place only partly fixes the issue.
