[Bugs] I have a session that deletes 2 million lines of code.

**Mood:** 😔
**Category:** Bugs

I have a session that deletes 2 million lines of code. When I toggle to that session, this entire app crawls to a halt -- everything becomes slow and unusable. I had to kill the app and ensure a different session was selected by default to get things normal again.

See: https://github.com/dotnet/java-interop/pull/1484

Start at the /chat path and reproduce the slowdown by selecting a session containing roughly 2 million lines of code, using app version 1.0.9 on Windows 10. Done means switching to that session no longer makes the app slow or unusable, without needing to kill the app.
