Summary
After we apply fixes, the source code might be transformed. And yet, we're using the unmodified source code to compute locations in some cases (e.g., for displaying parse errors, or Jupyter Notebook cells). This can lead to subtle errors in reporting, or even panics. This PR modifies the linter to use the transformed source code for such computations.
Closes #9407.
