Changing the default browser in the MATE settings does not affect the launcher on the bottom bar

Description

Trisquel provides by default a launcher to launch an installed web browser. However once a user installs more then one (through apt), the web browser launcher on the bottom bar will change away from Abrowser to what ever was installed.

The problem is that changing the preferred browser under: System > Preferences > Personal > Preferred Applications to another browser does not seem to affect this launcher.

The default browser option works for the rest of the OS (e.g. launching a link from Icedove). But for this one shortcut, it won't.
