Problem using full-page screenshot developer tool with certain websites

hi, I am using F12 developer tools to do full-page screenshot.

However, it does not work with all websites layouts like this https://www.coursera.org/learn/machine-learning/discussions/all/threads/f_8LcOlvEeSnBSIAC4s0zg (you need to have a coursera account and enroll as a student to check the full content)

Discussed about this on IRC a bit.

The page contains a scrollable container. The fullpage screenshot could not easily expand all possible containers with scrollbars and recompose them in a meaningful screenshot.

I tried using the “screenshot node” feature from the inspector, trying to target the node that was scrolled out. It creates a screenshot that has the correct height, but only paints whatever area was visible in the scroll container.
