Broken example CI runs #1132
Description
Problem description
An apparent upstream change causes LaTeX \Delta no longer to be recognized in matplotlib figure titles. As a result, current GH Actions for Example tests are broken.
Steps to reproduce
See #1127. Error message is:
interfaces/cython/cantera/examples/kinetics/blowers_masel.py
Traceback (most recent call last):
File "/opt/hostedtoolcache/Python/3.9.7/x64/lib/python3.9/site-packages/matplotlib/_mathtext.py", line 2277, in parse
result = self._expression.parseString(s)
File "/opt/hostedtoolcache/Python/3.9.7/x64/lib/python3.9/site-packages/pyparsing/core.py", line 1101, in parse_string
raise exc.with_traceback(None)
pyparsing.exceptions.ParseFatalException: Unknown symbol: \Delta, found '\' (at char 0), (line:1, col:1)
System information
GH Actions
Additional context
Avoiding LaTeX in examples is likely the easiest resolution (e.g. fix in #1129)
