For files with tab indentation, diff rendering on edit seems to get corrupted. I can reproduce it pretty easily just editing a python file with tab indentation. Asking the LLM to swap it back to space indentation seems to fix the diff view rendering. interestingly when I took screenshots with the built in SVG screenshot functionality, they looked correct.

The view when editing a file with tab indentation:

The view after swapping it back to space based indentation:
