Selecting a Dashboard to look at, the dashboard listing remains, and I see a very thin line at the bottom of the screen looking like a piece of dashboard. But unable to access any dashboard.
The dashboard list is overlaid on the existing dashboard view.
This is the expected behavior and can be reproduced across any browser or version.
It is reproducible in two cases:
In both cases, a part of the previously opened dashboard may still be visible at the bottom of the screen.
This indicates that you are still in the dashboard view and can return to the full dashboard view by clicking the close icon in the top-right corner.
