tikzplotlib Aspect ratio not exported

trafficstars

I am trying to preserve the aspect ratio being set for my figure, but it seems to be ignored. At the moment I manually add height=5cm,width=5cm to the axis argument (or specify it using the extra_axis_parameters), but an automated solution would probably be better as the docs for the figurewidth and figureheight explicitly state that not specifying them will try to preserve the aspect ratio - which seems to fail in my case.

Python code:

import matplotlib.pyplot as plt
import tikzplotlib

circle = plt.Circle((0, 0), 1)
figure, axes = plt.subplots(figsize=(5, 5))
axes.set_xlim([-1.5, 1.5])
axes.set_ylim([-1.5, 1.5])
axes.set_aspect("equal", adjustable="box")
axes.add_artist(circle)

figure.savefig("correct_output.png")
tikzplotlib.save(figure=figure, filepath="output.tex", standalone=True)
