With beta.3 Bootstrap brought back cursor: pointer for buttons. However when having menu items using <button> tags inside dropdown they still use cursor: default (see this example from docs). I believe it is a bug and menu items should also have cursor: pointer.
FWIW i agree...PR incoming
Same problem with Buttons in List Groups (example from docs)
