Basepair links not showing with forgi.visual.mplotlib.plot_rna

[mtod92]

Hello,

I am plotting a structure with the following script:

import forgi.graph.bulge_graph as fgb
import forgi.visual.mplotlib as fvm
import matplotlib.pyplot as plt

seq = "AAAACCGGGCCUUUUACCCCAAAUUGGAA"
mfe =  "((((..(((..)))..))))...((..))"
bg, = fgb.BulgeGraph.from_fasta_text("".join([">test\n", seq, "\n", mfe]))

fvm.plot_rna(bg, ax=None, offset=(0, 0), text_kwargs={}, backbone_kwargs={'color':'k', 'lw':2}, basepair_kwargs={'color':'black', 'lw':5, 'linestyle':':', 'edgecolor':'black', 'alpha':1}, lighten=0.5)

The structure looks just fine, and I can modify the backbone appearance with the keyword arguments passed to matplotlib.
Unfortunately, the basepair just do not show up.
I am playing around with all possible arguments (color, line width, lifestyle, edge color, alpha) to try and have them showing up, but it's not working.

Any help?

Thanks

P.s. I suspect this is because I am not explicitly passing a list of paired nucleotides to be connected, and it is not clear to me how to do that at this moment.
P.p.s. nevermind, bg.to_pair_tuples() shows that the base pairs are correctly captured, so the issue is in the visualization itself.
