warning in doc build: The fit may be unsuccessful (modeling tied constraints)

See original GitHub issue

Description

I noticed in the doc build for #11367 it failed due to a likely unrelated warning coming from the modeling package:

/home/docs/checkouts/readthedocs.org/user_builds/astropy/envs/11367/lib/python3.8/site-packages/scipy/optimize/optimize.py:282: RuntimeWarning: Values in x were outside bounds during a minimize step, clipping to bounds
  warnings.warn("Values in x were outside bounds during a "
/home/docs/checkouts/readthedocs.org/user_builds/astropy/envs/11367/lib/python3.8/site-packages/astropy/modeling/fitting.py:1166: AstropyUserWarning: The fit may be unsuccessful; check fit_info['message'] for more information.
  warnings.warn("The fit may be unsuccessful; check "

I thought it might be a fluke, but locally I get the same warning, as well as

/home/embray/src/astropy/astropy/astropy/timeseries/__init__.py:docstring of astropy.timeseries.BoxLeastSquaresResults.popitem:: WARNING: py:class reference target not found: (k, v), remove and return some (key, value) pair as a

There is something fishy going on here.

Putting a traceback.print_stack() in the did not parse as fits unit unit warning confirms that those uncatched warnings come from the plots (matplotlib.sphinxext.plot_directive).

@dhomeier fixed the existing warnings in #12788 . Hopefully we are more vigilant going forward so they don’t creep back in. Thanks, Derek!
