Helix on ConEmu misinterprets arrow keys, alt keys

[Zoybean]

Summary

When using the arrow keys to navigate, or using alt-key inputs, helix and the underlying ConEmu terminal mishandle the inputs, and mess with the display.

I cannot seem to reproduce this on my other PC running the same version of ConEmu, and this does not affect vim or other editors on conemu on the same machine, or helix in the cmd terminal, so it appears to be a bug in the interaction between helix and conemu specifically on this machine.

Reproduction Steps

I tried this:

1. hx .
2. navigate file list with arrow keys
3. esc i
4. navigate buffer with arrow keys

I expected this to happen:

The list selection / cursor position changes in response to my input

Instead, this happened:

I enter normal mode (and the file list is closed) as if I had pressed esc, and either:

• I enter the [ sub-mode
• the character under the cursor is visually changed (though the buffer is not edited) depending on the key pressed: either to a [ or to one of A,B,C,D for up, down, right, left respectively.

After closing helix, the terminal had the typed input seemingly corresponding to the unexpected characters that displayed while helix was open, e.g.: BCB[AA[AADCA[AAAA[AABD[ABBB
