Annotations with duration can be set as Bookmark
Initially, bookmarks were not supposed to have a duration and adding one to a bookmark is prevented.
Annotations with duration can be toggled to bookmark in AnnotationItem though. This leads to the annotation not showing up in neither the regular annotations lane nor in the bookmarks lane.
A fix that would not break current data that now might contain bookmarks with duration and still prevent further creation of such bookmarks would be to:
- grey out the bookmark toggle in AnnotationItem for annotations with duration, with explaining tooltip
- show bookmarks with duration as regular bookmarks in the bookmarks lane to keep existing invalid bookmarks usable
