Crash while navigating jumplist after reload-all

[jonner]

Summary

I was making some modifications to some code. I had a bunch of buffers open with a lot of changes, and I had been navigating through the code for quite some time. At some point I decided to abandon the changes, so from another terminal, I ran git stash to revert all of my uncommitted changes. Then from within helix, I did :reload-all to revert the state of the open files within the editor to match the state of the files on disk. But when I navigated the jumplist by pressing ctrl+o a couple times, I got a crash.

thread 'main' panicked at /usr/share/cargo/registry/ropey-1.6.1/src/slice.rs:360:41:
called `Result::unwrap()` on an `Err` value: Char index out of bounds: char index 12298, Rope/RopeSlice char length 9098
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

Reproduction Steps

I tried this:

1. hx
2. Edit a bunch of files, navigate the code via jumping to symbol definitions via lsp, etc
3. git stash
4. :reload-all
5. ctrl-o several times

I expected this to happen:
navigate backwards in jumplist stack

Instead, this happened:
crash
