Remove arrows on system tray menus in gnome

I've recently upgraded to Ubuntu 13.10 with Gnome and have found the behaviour of the context menus on icons in the system tray behaves differently.

For applets which normally have a large number of menu options (e.g. notes in Tomboy or files in Dropbox) rather than display all the menu icons now only 5 or 6 are displayed and up/down arrows are displayed to scroll to the rest.

Is it possible to revert this behaviour so all menu options are showing without the need to scroll?

This extension/work around could be of some help if you have to get rid of the drop down menus which are default in gnome 3.8+ gnome-shell-remove-dropdown-arrows

There's this awesome extension called TopiconsPlus. Once installed it moves all those "legacy" icons to the menubar.
