electron: Memory leak when opening and closing windows

Issue Details

• Electron Version:
  • 5, 6, 7, 8
• Operating System:
  • Windows 10
• Last Known Working Electron version:
  • ?

Expected Behavior

Opening and closing window should not increase memory

Actual Behavior

Memory will increase for each window even after the window has been destroyed

To Reproduce

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

const init = () => {
	let browserWindow2 = new BrowserWindow({
		show: true,
	});
	let j = 0;
	const interval = setInterval(() => {
		j++;
		if (j > 10) {
			clearInterval(interval);
		}
		for(let i = 0; i < 20; i++) {
			let browserWindow = new BrowserWindow({
				show: true,
			});
			setTimeout(() => {
				browserWindow.close();
			}, 5000)
		}
	}, 1000);

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

The above code snipped should not result in more memory than just opening a single window. I also tried to call the garbage collector manually and I also tried browserWindow.destroy(). No difference.
