"Slow" navigation in insert mode -> completions that mangle items

[nuke-web3]

Summary

Related to #8263 , when I am navigating with arrow keys in insert mode "slowly" enough for the lsp to suggest a term for where the cursor is, the lsp result is injected where I intended to just keep navigating.

This is a massive pain as I am in insert mode and working, with this unwanted junk injected... and now I cannot undo only that junk, but the entire insert 😮‍💨 - so I have to manually delete and replace the item. Big waste of time.

Reproduction Steps

1. enter insert mode
2. "slowly" move up/down lines with a cursor inside some item
3. LSP autocomplete injects and cycles options, where you meant to move up/down a line.
4. you cannot u in normal mode to undo just that injection, but the whole insert.
5. Manually edit the injected junk to get back the original item

Helix is a modal editor. You are not supposed to move in insert mode. Normal mode is intended for movement.

One "solution" is to notice this is happening and press C+c to cancel the injection. But that is also very un-ergonomic
