Caught panic: runtime error: index out of range [3] with length 3

[j-mnr]

:wave: Hello :smile:

While trying out some components from Bubbles I ran into an issue with the text-area component -- Full example on playground -- there were two things I noticed.

1. When I used arrow keys the character [ would make itself appear as if I typed it in
2. When I held down the Down arrow key a panic would happen.

Caught panic:

runtime error: index out of range [2] with length 2

I'm very new to bubbletea but I'm guessing this isn't expected to happen. Here's the entire go.mod file

Let me know if there's anything you need to know about concerning my terminal or keyboard.
