'after' decoration type shown before cursor

[kieferrm]

VS Code version:
1.43.0-insider
e6a45f4
x64

I use the following extension code. (Also available at https://github.com/kieferrm/testplan-items/tree/master/editor-decorations.)

import * as vscode from 'vscode';

export function activate(context: vscode.ExtensionContext) {

	const beforeType = vscode.window.createTextEditorDecorationType({
		before: {
			contentText: 'before',
			color: '#e54910'
		}
	});
	const afterType = vscode.window.createTextEditorDecorationType({
		after: {
			contentText: 'after',
			color: '#7ba7ce'
		}
	});


	let disposable = vscode.commands.registerCommand('extension.setBeforeDecoration', () => {
		const selection = vscode.window.activeTextEditor?.selection;
		const position = selection?.start
		if (position) {
			const range = new vscode.Range(position, position);
			vscode.window.activeTextEditor?.setDecorations(beforeType, [range]);
		}
	});
	context.subscriptions.push(disposable);
	
	disposable = vscode.commands.registerCommand('extension.setAfterDecoration', () => {
		const selection = vscode.window.activeTextEditor?.selection;
		const position = selection?.start
		if (position) {
			const range = new vscode.Range(position, position);
			vscode.window.activeTextEditor?.setDecorations(afterType, [range]);
		}
	});
	context.subscriptions.push(disposable);

	disposable = vscode.commands.registerCommand('extension.removeDecorations', () => {
		vscode.window.activeTextEditor?.setDecorations(beforeType, []);
		vscode.window.activeTextEditor?.setDecorations(afterType, []);
	});

	context.subscriptions.push(disposable);
}

export function deactivate() { }

Use the following input in an untitled editor:

aaa
test()
bbb

Put the cursor between the parentheses and

1. Set Before Decoration
2. Remove Decorations
3. Set After Decoration
4. and 3) create the same result, i.e. appear before the cursor. I'd expect 3) to appear after the cursor.
