Forwarding the arguments of replacePreviousChar to default:replacePreviousChar causes text jitter during ime composition.

Code to reproduce the issue:

vscode.commands.registerCommand("type", (type) => {
    vscode.commands.executeCommand("default:type", type);
});
vscode.commands.registerCommand("replacePreviousChar", (args) => {
    vscode.commands.executeCommand("default:replacePreviousChar", args);
});

Hi @xiyaowong thank you for filing this issue. I am currently trying to reproduce this issue, but after having configured neovim, I get the following issue 'neovim gets disconnected' as soon as I reload the window. I saw that in the past two weeks quite a few people have filed this issue to the neovim repo. It would seem like this is an upstream vim issue?

@aiday-mar "Neovim gets disconnected" is an upstream issue with Neovim, but it is unrelated to this issue. The jitter problem mentioned in this issue has been longstanding, and it also occurs with vscodevim.
