Bug summary
Placing non-standard tex commands like \unit{mm} from siunitx package on
Does it still check stuff in $ signs for valid commands?
Code for reproduction
import locale
import matplotlib
import matplotlib.pyplot as plt
matplotlib.use('TkAgg')
plt.style.use('matplotlib_style.mplstyle')
# text.usetex: False
# text.latex.preamble: r'\usepackage{amsmath}\usepackage{siunitx}'
locale.setlocale(locale.LC_ALL, '')
fig, ax = plt.subplots()
ax.plot([0], [0], 'x')
ax.set_xlabel(r'$\Delta x$ \unit{mm}') # <- does work
ax.set_xlabel(r'$\Delta x \unit{mm}$') # <- does not work
plt.savefig('fig.svg') # plt.show() does not work eitherActual outcome
