The issue, presumably the PR (linked at the top of the issue because of reference).
Look at the code change. It gets inputs and loops over them and seems to do an in-place fixup. But the code indent is wrong, and it even changed the function definition of the unrelated next function. In Python, the indent-logic-significance language.
I assume they briefly showed the code on stage. Even then it should have been obvious to any developer. py file, messy indent, changes unrelated function.
Please correct me if this is the wrong PR.
