I use plenty of folders in my bookmarks bar. Now every time I left-click on one to select a saved bookmark, the size of the drop-down menu varies greatly and is cutting the names of the bookmarks. Sometimes it's very narrow, cutting words after 8 characters or so. I can't understand the rationale for the applied size. It used to adapt based on the longest name in the group (up to a limit).
