SSH arrow keys work everywhere except parted

I'm using a Raspberry Pi 3 with LibreELEC 7.0.2.

When I connect via SSH (from PuTTY on Windows), the arrow/home/end keys work correctly within the shell as well as within vi. However, once I enter parted, the arrow/home/end keys start displaying characters such as:
(parted) ^[[A^[[B^[[D^[[C^[[1~^[[4~

Using the exact same SSH settings to connect to Arch Linux on another Raspberry Pi and use parted there with arrow/home/end keys just fine.

From some related searches:

It sounds like the problem may be related to readline. Is LibreELEC's parted compiled with readline disabled?

parted isn't built with readline support

LibreELEC.tv/package.mk at master · LibreELEC/LibreELEC.tv · GitHub

Thanks. Is changing that setting the right fix for this bug then? (Or is there a reason not to make that change?)

It's really not needed for our purposes.

Sorry, I'm not quite following. Could you elaborate a bit?

(Trying to understand the philosophy of what's included in LibreELEC - I was thinking parted was only useful for SSH-like scenarios, but maybe there's automated usage that wouldn't benefit from arrow keys? In other words, is the reason for including parted different from the reason shell/vi are included along with arrow key support?)

Thanks,

David

parted is included because it is used for resizing partitions upon initial boot

It is still usable without readline.

That makes sense. Thanks for the explanation.

There is also fdisk

BTW, I wasn't able to find fdisk, at least by default:

LibreELEC:~ # fdisk
-sh: fdisk: not found
