I can't help with more than a small clue on this bit:

This feels like a terminal emulation issue. The VT52 escape sequence
for left-arrow is ESC-D, the ANSI+reset is ESC-[-D, and ANSI+set is
ESC-O-D. I think pressing left arrow is generating an ESC-O-D sequence,
but the terminal is processing the sequence as separate inputs.
Probably because it expects ANSI+reset.

ESC drops you out of insert mode
O inserts a line above the current one
D is a D :-)

I would half expect you to get an A for up arrow, a B for down arrow
and a C for right arrow...

Try this:
- type "cat"
- press ENTER
- press left-arrow

I think you will see a caret, two left square brackets, and a "D".

Investigate whether your terminal supports alternative emulations.

This can also happen when the components of a sequence are too far
apart. The emulation may decide they are not a sequence. That seems
very unlikely in your case.

The line spacing could be another emulation problem, for example if the
emulation treats carriage return as newline.
