Bug summary
The SymPy 1.5 documentation was built with matpltolib < 3.2, see the results here:

The SymPy development documentation (SymPy master branch) is now built with matplotlib 3.2, see the results here:

I've been documenting the issue over at SymPy here: sympy/sympy#19051
Code for reproduction
Note that SymPy has a wrapper around various plotting libraries and it will run matplotlib as the backend by default. I have not yet isolated what underlying mpl code in the SymPy wrapper is specifically affected.
from sympy import symbols
from sympy.plotting import plot
x = symbols('x')
p1 = plot(x*x, show=False)
p2 = plot(x, show=False)
p1.append(p2[0])
p1.show()Actual outcome
# If applicable, paste the console output here

Expected outcome
Matplotlib version
- Operating system: Ubuntu 18.04 and 19.10
- Matplotlib version: 3.1 and 3.2
- Matplotlib backend (
print(matplotlib.get_backend())): - Python version: 3.6-3.8
- Jupyter version (if applicable):
- Other libraries: SymPy 1.5
Checked with MPL from conda-forge.
