This issue can be solved by adding the following to metacatui.css under the heading /* Logged-in view and user controls in navbar */

    /* Keep logged-in nav dropdown from going off page right */
    .navbar-inner .dropdown-menu {
        left: unset;
        right: 0;
    }

I will create a PR for this shortly.

Working with the new SI theme has reminded me that this should be added to the default theme.
