I made a custom shaped text container to put my text into. When it is empty, the outline is invisible in Keyline/Outline view. Even if I add a stroke to it, it remains invisible. Seems like this is a bug. Even when the custom shaped text containers have text, there is no outline visible in Outline/Keyline mode. One has to select the container to view the blue outline, which is not useful when trying to find an empty container. Thanks for reviewing this bug and all you do.
