The label depends on the backend, so we just want the dummy
backend used here. **UNFORTUNATELY** - either because the
override_plot_backend fixture is not well written, the current
approach to setting up the plot backend does not handle it being
swapped out (e.g. see #1191), or a combination of the two - the
test doesn't work well if there is a non-dummy backend loaded.
