Window freezes when opening multiple dialogs

[bpasero]

Due to electron/electron#11323

Steps:

• have an extension with the following code and run it:

'use strict';
// The module 'vscode' contains the VS Code extensibility API
// Import the module and reference it with the alias vscode in your code below
import * as vscode from 'vscode';

// this method is called when your extension is activated
// your extension is activated the very first time the command is executed
export function activate(context: vscode.ExtensionContext) {

    // Use the console to output diagnostic information (console.log) and errors (console.error)
    // This line of code will only be executed once when your extension is activated
    console.log('Congratulations, your extension "test-ts" is now active!');

    // The command has been defined in the package.json file
    // Now provide the implementation of the command with  registerCommand
    // The commandId parameter must match the command field in package.json
    let disposable = vscode.commands.registerCommand('extension.sayHello', () => {
        // The code you place here will be executed every time your command is executed

        // Display a message box to the user
        console.log(1)
        vscode.window.showSaveDialog({
        });
        setTimeout(() => {
            console.log(2)
            vscode.window.showInformationMessage("message", { modal: true });
        }, 1000);

    });

    context.subscriptions.push(disposable);
}

// this method is called when your extension is deactivated
export function deactivate() {
}

=> the window freezes
