Buttons not reactive + List of sessions taking a while to load

[antoinefalisse]

@olehkorkh-planeks, I always have this issue that I need to click perfectly in the center of the button to have it to react. Not only the analysis button in the example video below, more general than that. Also, the session list on the landing page sometimes takes a while to load. More details in the video below. Could you take a look? Thanks?
