Thin space missing after mathtext operators #17852
Description
Bug report
Bug summary
Mathtext operators (\log, \max, etc.) should insert a thin space after themselves (if followed by ordinary characters, not if followed by an open parenthesis, see https://tex.stackexchange.com/questions/225922/spacing-rules-for-operatorname/225924#225924), but currently it does not.
Code for reproduction
from pylab import *
figtext(.5, .6, r"$\log 6$ (usetex)", usetex=True)
figtext(.5, .5, r"$\log 6$ (current)")
figtext(.5, .4, r"$\mathdefault{log}\,6$ (manual thin space)")
figtext(.5, .3, r"$\mathdefault{log}\ 6$ (manual full space)")
show()Actual outcome
Note the missing thin space between "g" and "6" in the current behavior.

Labeled this as hard because the fix is going to involve diving into the tex parser in https://github.com/matplotlib/matplotlib/blob/master/lib/matplotlib/mathtext.py but good first issue because there is no API design and should not require any changes outside of the

Is this done since #17890 was merged?

I think sub/superscript handling is still a problem (#17890 (comment)).
