When I set an element’s CSS position to properties that remove it from the normal document flow (such as absolute or fixed), the exported PDF displays blank content.
Steps to Reproduce
1. Create an element with position: absolute or position: fixed.
2. Try exporting the page to PDF.
3. The generated PDF file is empty (blank).

Expected Behavior
The element should render normally in the PDF output.

Actual Behavior
The PDF shows a blank page.
