`AttributeError: 'Axes' object has no attribute '_axes_class'` after update to matplotlib-base 3.7.0

Problem description:
After updating from matplotlib-base-3.6.2 to matplotlib-base-3.7.0, the following error occurs inside a previously working notebook:

Problem analysis:
After some testing with fresh conda environments, I've narrowed the problem down to the most recent version of matplotlib-base-3.7.0. In a clean install, there is only matplotlib-base-3.4.3 installed alongside GWpy. Up to matplotlib-base-3.6.3 there are no errors. After upgrading to matplotlib-base-3.7.0, the error occurs.
I assume some change there is incompatible with GWpy and require some changes to adapt.
Note: Conda does not provide matplotlib-3.6.3 and I couldn't test it specifically but everything works with this version on my other machine!
Note: In matplotlib-3.7.0 I also get the following deprecation warning. I don't know if they might be related:
/tmp/ipykernel_99704/3175995638.py:10: MatplotlibDeprecationWarning: The get_cmap function was deprecated in Matplotlib 3.7 and will be removed two minor releases later. Use ``matplotlib.colormaps[name]`` or ``matplotlib.colormaps.get_cmap(obj)`` instead. Minimal code example:
Example taken from here: https://gwpy.github.io/docs/latest/examples/timeseries/qscan/
from gwpy.timeseries import TimeSeries
data = TimeSeries.fetch_open_data('H1', 1126259446, 1126259478)
qspecgram = data.q_transform(outseg=(1126259462.2, 1126259462.5))
plot = qspecgram.plot(figsize=[8, 4])
ax = plot.gca()
ax.set_xscale('seconds')
ax.set_yscale('log')
ax.set_ylim(20, 500)
ax.set_ylabel('Frequency [Hz]')
ax.grid(True, axis='y', which='both')
ax.colorbar(cmap='viridis', label='Normalized energy')
