Mapping `C-[` and `C-]` fails

[augustebaum]

Summary

I wanted a quick way to switch buffers so I added this to my config, in the [keys.normal] section:

"C-[" = ":buffer-previous"
"C-]" = ":buffer-next"

The buffer does not switch, instead of C-[ helix saves the current buffer, and on C-] nothing happens. I tried A-[/] as well and A-] works, but not the other (triggers the [ menu instead).
Has anyone run into this before or would otherwise know how to debug this?

I tried visualising the keypresses using Karabiner-EventViewer and everything seems normal.

I opened an `md` file, opened another with `:open`, then run `A-]` a few times (which worked as intended), then `A-[` a few times (which failed), then quit. I don't think there is much to be found here...

These keys are another instance of #1085: the keycodes that the terminal gives are confused with other inputs. For example C-[ is interpreted as Escape and C-] as C-5. I'll close in favor of #1085.

These are all interpreted correctly with #4939
