(Mac) Opening the Bookmarks menu whilst the Library window is open causes recently bookmarked listener to remain which can impact performance
I noticed this whilst having a general look at the performance of removing bookmarks. STR: - Open the Library window - Set up a folder with a lot of bookmarks (e.g. ~600ish) - Open and close the bookmarks menu - Set up the profiler - Delete the newly created folder. Look at the profile -> There's lots of references to _populateRecentBookmarks and that takes a long time. It only occurs on Mac, due to how the context menus work (Mac doesn't have context menus on the toolbar menus). This bug was caused by bug 1248268 - it added an option for hiding or showing the recent items. However, in the Library window, the context items are not there. As a result, attempting to deal with updating the context menu causes an exception and the listeners don't get removed.
