(Python) Syntax highlighting bug in Python REPL

Describe the issue

While posting an answer on Stack Overflow, I noticed a syntax highlighting bug in the code block showing my Python program in a REPL environment. I posted the issue on Stack Exchange Meta here which shows the bug clearly.

Which language seems to have the issue?

Python.

Are you using highlight or highlightAuto?

I am using Stack Overflow highlighting with an explicit python tag.

Sample Code to Reproduce

>>> class A:
...     @classmethod
...     def f(cls): return 'A.f'
... 
>>> class B(A):
...     @classmethod
...     def f(cls): return 'B.f'
... 
>>> b = B()
>>> b.f
<bound method B.f of <class '__main__.B'>>
>>> B.f
<bound method B.f of <class '__main__.B'>>
>>> b.f()
'B.f'
>>> B.f()
'B.f'
>>> super(B, b).f
<bound method A.f of <class '__main__.B'>>
>>> super(B, B).f
<bound method A.f of <class '__main__.B'>>
>>> super(B, b).f()
'A.f'
>>> super(B, B).f()
'A.f'

Expected behavior

Additional context

I think what is happening here is the quotes around the class name or the <> in the output is messing up the rest of the output. Compare highlight.js on SO

with the highlighter used by GitHub

All that stuff shouldn’t be orange. I just ran into what looks to be the same bug here https://stackoverflow.com/a/3560349

Our developer tool is great (and what I was snapping) but it’s not just laying around online unfortunately. Perhaps in the future.
