Simplify the scrolling behaviour of the annotation stream
Currently the scroll position in the annotation-stream is set by the ID of an annotation or by the time of the timeline. We also need to change the scroll position while commenting. I would suggest to use the quasar scroll Utils. https://v1.quasar.dev/quasar-utils/scrolling-utils#introduction
If we don't use a q-scroll-area we could build one central scrolling function which would work in the live-annotator, post-annotator and timeline-viewer.
