When editing components on a page with several levels of areas and components in Magnolia, the experience is a bit flickery as edit bars that were previously displayed are getting hidden when moving further down the hierarchy.

An example of this is shown in this video:

I suggest that all edit bars on the active path (between root and the active position) stays displayed, to avoid flickering and to provide a better context of where the active component is located.
To further improve the experience I also suggest that:

• clicking an edit bar will always open the contained level of edit bars
• also display edit bars of siblings to the areas and components of the active path

Here is a video showing the same page with this improved behaviour:
