The panel which opens when clicking the "Shield" icon on a site to show ranking options, tracking info, etc. sometimes includes a lot of information, which does not fit on smaller screens, causing the bottom to be cut off - See screenshot.
This is easier to reproduce by zooming in on your browser.
In theory, this menu should show a scroll bar to show more information.
All content should be visible, either by a scroll bar or by showing less content to fit the available screen space.
