When using accessibility tools like screen magnifiers, dynamic screen content can be quite problematic. In particular content, which only appears if you interact with elements somewhere else on the screen. That is the case, for example, with the current implementation of tooltips used by audiobookshelf. This patch provides a slight adjustment, keeping the tooltips open if you hover over them. This allows users to have better access to the content.
