Why is there a generic folder icon for Library in the "Go" menu? Usually, when in the Go menu in Finder, there are icons for each item, for example

However, when I hold the option key and Library shows up, it has a generic folder icon instead of a court-like icon:



I have since upgraded to El Capitan, but it has been that way since Yosemite. The only thing I can think of that may have caused this is setting the ~/Library folder to nohidden using chflags, but setting it back to hidden does not fix the issue.

Is this new behavior(I doubt it), or a glitch on my part? How could I fix it?
Unfortunately, there is no Sidebar icon for the Library folder in Yosemite and El Capitan. The sidebar icons are used for the Go menu items as well.

The icon that was used in the past in the  (Mavericks and before), was (to my knowledge) ToolbarLibraryFolderIcon.icns, which does not exist anymore.

You can view the Sidebar icons that do exist in /System/Library/CoreServices/CoreTypes.bundle/Contents/Resources. They are named in the format Sidebar&lt;FOLDERNAME&gt;Folder.icns.

Interestingly, the Library folder icon (for the folder itself in Finder) does still exist, as LibraryFolderIcon.icns
