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, seehttps://tex.stackexchange.com/questions/225922/spacing-rules-for-operatorname/225924#225924), but currently it does not.

Code for reproduction

frompylabimport*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.
