Twincolorbar missing ticks

It seems that there is an issue with twin ticks on the colorbar, at least since the version 0.10.0:

fig = plt.figure(figsize=(12, 9))
ax = fig.add_subplot(projection=GANYMEDE)

ax.add_collection(janus_flyby.fovs(facecolors='alt',
                                   vmin=500, vmax=10_000,
                                   sort='dist', reverse=True))

ax.colorbar(vmin=500, vmax=10_000, label='alt', extend='max')
ax.twin_colorbar(label='JANUS pixel scale',
                 ticks=[25, 50, 75, 100, 125, 150],
                 format=janus_flyby.observer.ifov_cross_track * m_pix_ticks)

ax.set_title('JANUS footprints during 2G2 flyby (Feb. 13th 2032)');

This could be related to a matplotlib version upgrade.

The expected figure should look like this:

However, the issue is not present in MAJIS FOV example 🤔 in 1.0.0:
