Override Disabled Scrolling on Cookie Pop-up Boxes

I save lots of web-pages using SingleFile so I always have a copy, but some pages retain a pop-up cookie or other kind of pop-up. You can remove these easily enough from the saved HTML, but sometimes you still can’t scroll.

I insert the below CSS snippet into the saved HTML (anywhere within the <head></head> tags) and this usually overrides the stupid lack of scrolling.

<style>
	body {
	    overflow: auto !important;
	}
</style>
