Description
In the bookmark menu (the one you directly open with the bookmark icon in the toolbar), the top two icons for "view bookmark sidebar" and "search bookmarks" are in a fixed spot. When you have more bookmarks in the menu than fit your screen, you can scroll the menu. But the top two icons stay in their original spot so they overlap with other icons.
