Pick the actual container
Turn on Capture a scrolling area under Full page, then point at the panel. The picker highlights an element that really scrolls; the up arrow widens to an enclosing scrolling element. Escape cancels without capturing.
After the pick
The standard engine scrolls the selected element vertically, captures its content, and restores both the panel and the page to their starting positions. It does not resize the app to force more content into view.
A useful check
- Open the app at the panel you need.
- Choose Full page and turn on Capture a scrolling area.
- Pick the panel, capture, and check that its last row appears in the result.
