Ben, it looks familiar, and related to a bizarre feature that I thought
we had eliminated--but I just tried it with master, and it's still
there. Maybe the change is still languishing in an open PR.
Sean,
I think you are understandably misunderstanding the confusing annotation
API.
ax.annotate( r"$\mathbf{" + label + ")}$",
xy=(0.9, 0.9),
xycoords="axes fraction",
fontsize=14 )
If you change your annotation call to the simpler version above, I think
it will do what you intended.
