The AnnotationEditor does not remember the shown annotations when the Cas Editor is restarted

The Annotation Editor does not remember the shown annotations when the Cas Editor is restarted. This bug is confusing for new users, because the Annotation Editor looks different compared to the last time a user used it. For more advanced users it is annoying because by default all annotations are shown in the Annotation Editor but it is common to un-select some to focus on a specific task, the un-selection must be redone after every start of the Cas Editor.
