"Take Screenshot of the Entire Page" includes elements outside page bounds, e.g. elements with negative top or left, or negative bottom or right values. I think this can only be elements with position: fixed or position: absolute.
Elements with position: absolute are visible in the screenshot while elements with position: fixed are not, but the screenshot is extended to the edges of elements with either position value.
Steps to reproduce:
Real-world site:
- Navigate to YouTube.com and open a video
- Use "Take Screenshot of the Entire Page" (Ctrl + Cmd + 2)
- Observe that the screenshot includes a button that is way outside page bounds and the screenshot is larger the user-accessible page
Minimal example:
- Open this test page:
- Click the button to move the divs out of the bounds of the page
- Use "Take Screenshot of the Entire Page" (Ctrl + Cmd + 2)
- Observe that the screenshot has expanded to the minimum size to include both the outside page bounds divs
- Observe that the
position: fixed div is not visible (despite the screenshot expanding to include it), but the position: absolute div is visible
Expected behavior:
"Take Screenshot of the Entire Page" includes only user-accessible space
