Steps to reproduce the problem:
1. Use devtools to inspect any element inside a scrolling container (ex: in a web chat app) that is large enough to get visually truncated by the container
2. Cmd-Shift-P, choose "Capture node screenshot"

What is the expected behavior?
Screenshot contains the full contents of the node.

What went wrong?
Screenshot is sized according to the full bounds of the node but only contains the parts of the node that are visually on screen already.

You need to manually manipulate the scrolling container to be tall enough in order to capture the full height of the node in a screenshot.

Did this work before? N/A
