A temporary workaround (or like Thunar used to do this before; and this method still works):
create a ".gtk-bookmarks" text file in your home directory and add the shortcuts manually in the format:
file://PATH_TO_YOUR_FOLDER
example:
file:///home/username/Documents/ file:///home/username/Pictures/
and so on.
save and reopen thunar, bookmarks should be in the side panel again.
