Full page screenshot can change page content

Example report (Legacy navigation)

In the example above, the page shows different content in the full page screenshot than it does in the timeline frames. The page detects a different viewport width and changes the content (e.g. side margins).

The FPS gatherer should keep the content width fixed so it better reflects the content Lighthouse audited.
