Ropey crash when pressing . key

[jobukkit]

Summary

I managed to crash Helix three times by showing hover documentation for an incompletely written Rust function call, then clicking somewhere, then pressing the . key. I can no longer recreate the crash now though, so I'm not sure what specific circumstances led to it and whether any action before pressing . was even relevant.

Can confirm the same / a very similar error happening here:
