Subscripts and superscripts not saving in .tiff files

[jamiebull1]

I'm trying to create a .tiff with axis labels which include sub and superscript notation. I've used the $ notation $kgCO_2e/m^2$' to enclose the label and it shows up fine in the interactive output. It also saves as expected when saved to .png. However when saving to .tiff it shows up as the full text kgCO_2e/m^2.

The following snippet reproduces the problem.

import matplotlib.pyplot as plt

xs = [1,2]
ys = [2,3]
fig = plt.figure(figsize=(9,7))
ax1 = fig.add_subplot(111)
ax1.plot(xs, ys)
ax1.set_ylabel('$kgCO_2e/m^2$')
plt.show()

Looks like this was fixed by #1770.

@jamiebull1 If I am mistaken, please feel free to reopen this issue.
