This is lower priority and impacts the user experience.
For maps with long legend panel, it is sometimes helpful to hide the legend when scrolled down. However, the map title also scrolls (even though the hamburger menu on the legend panel does not). This makes it more difficult to hide the legend, for example, in order to claim some space so popup does not cover the active map. I don't even know if this is possible.
