[Bug]: No longer possible to set insecure cookies

main.js

const electron = require("electron");
const { app, BrowserWindow } = require("electron");
const path = require("path");

function init() {
	let browserWindow = new BrowserWindow({
		show: true,
		webPreferences: {
			partition: "persist:test-2",
		}
	});
	const session = electron.session.fromPartition("persist:test-2");
	session.cookies.set({
		name: "testcookie",
		value: "testvalue",
		domain: ".testdomain.com",
		path: "/",
		url: "http://testdomain.com",
	}).then(() => {
		console.log("setting cookie success");
	}).catch((e) => {
		console.error(e);
	});
}

app.on("ready", () => {
	init();
});
