Windows IME confused when typing next to replacements

[lishid]

When typing full-width punctuation characters at the exact spot that a replacement has happened, the Chinese IME on Windows ends up doing really weird things. I think it's getting confused by the ​.

Basic test case:

const {EditorState, EditorView, basicSetup} = CM["@codemirror/basic-setup"];
const {WidgetType, Decoration, ViewPlugin} = CM["@codemirror/view"];
const {StateField} = CM["@codemirror/state"];
let text = '1\nasdfasdf\n3\n4';
let decos = Decoration.set([Decoration.replace({}).range(4, 8)]);
let plugin = ViewPlugin.define(view => ({view}), {decorations: v => decos});
let state = EditorState.create({
	doc: text,
	extensions: [basicSetup, plugin]
});
view.setState(state);

Same thing happens when using Windows's emoji tool:

Really sorry to bother, is there any update on this issue?

Hope it could be fixed soon sincerely.
Desperately!

This is likely the same problem as https://discuss.codemirror.net/t/entering-cjk-with-placeholder-causes-problems-with-the-first-character/3876 . It indeed seems like the zero-width spaces are ruining everything again. I'm going to try and see if I can replace that hack with another less leaky hack.

I believe patch codemirror/view@d50dc90 solves this.
