Thank you for providing detailed steps and environment information regarding the full-page screenshot issue with iframes.

It appears that when capturing the full page, the resulting screenshot (full-page.png) is capturing the iframe container as blank white, even though the content within the iframe is correctly rendered and visible when capturing the viewport or the element itself.

The provided steps are clear, and the environment details (Playwright v1.59.1, Node v18.19.1, Ubuntu 24.04.4) are helpful for reproduction.

This suggests a potential discrepancy in how the full-page capture mechanism interacts with the rendering context of embedded iframes, especially for dynamic content like video players.

To help narrow down the scope, could you confirm if this behavior is observed with other types of if
