Issue Details

• Electron Version: 5.0.7
• Operating System: Windows 10

Expected Behavior

Based on the documentation, I expect that navigating to "about:blank" will trigger the webcontent’s will-navigate event.

Actual Behavior

will-navigate does not get triggered.

The docs make no mention of "about:blank" being an exception, and so I expect that will-navigate should get emitted when navigating to it.

Either this is a documentation error, or it’s a bug with will-navigate.

To Reproduce

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

async function onReady() {
	const mainWindow = new BrowserWindow();
	const view = new BrowserView();
	view.webContents.addListener("will-navigate", (e, url) => {
		console.log("navigating to: " + url);
	});
	mainWindow.setBrowserView(view);
	await view.webContents.loadURL("https://google.com");
	view.webContents.openDevTools();
}

app.on('ready', onReady)

After npm starting, in the devtools, run location = "https://google.com". Notice that we log it.

Then run location = "about:blank". Notice, that there’s no log.
