Inputting too quickly after exiting insert mode causes desync

Exiting insert mode and attempting to navigate too quickly causes the neovim and vscode buffers to de-synchronize. I happen to have the escape key bound to my home row, so I’ve been able to consistently trigger this bug.

I started experiencing this bug a couple days ago, not sure of the exact date, unfortunately. I can confirm this issue is reproducing with all neovim plugins disabled. I am using plugin version v0.0.52

This is my current neovim version string (nightly from 1 day ago, issues predate any recent upgrade):

Seems to be working for me so far, I can no longer reproduce using the given PR. I’ll continue to use it and will report back if I encounter any new issues that seem to be coming from the new changes.
