Open the right tab for the More... command

Partially fixed by Caolán in
3ac80237f310366afef0f7b6c427889d652bd369.

Remaining issues are the paragraph submenu, and the top
menu for both selection and paragraph. Also fixed for
the drawing text and annotations shells (including the
regression created by the above commit, that the dialog
didn't show at all).
