Additional Information

Corrects the placement of resize hit targets for frameless windows on Windows, which are supposed to be outside the window at the sides and bottom, not inset into the web content.

When I create a simple window

const mainWindow1 = new BrowserWindow({
		x: 0,
		y: 0,
		width: 1000,
		height: 600,
		show: true,
		frame: false,
	});

I can still see a few pixels of resize area being within the content area. The area does go outside of the window but starts within the content area.
Is this intended?

@t57ser Thanks, you are correct that the handles should only be on the outside.
