QPdfView mouseEvents don’t have correct position when scrolled

When the QPdfView is zoomed so that it needs scrollbars and area is scolled away from (0,0) the mouseMoveEvent and mouseReleaseEvents have incorrect position. Because of this links in the pdf file can’t be clicked.

The issue can be reproduced using the qtwebengine\examples\pdfwidgets\pdfviewer example and the attached pdf file.

Steps to reproduce:

• Launch attached example QTBUG-131443.zip
• Click the “Jump to page 2” link on the first page
• Note: Jumps to page 2
• Scroll the second page up so that the “Jump to page 1” is still visible
• Click the “Jump to page 1” link on the second page
• EXPECTED: Jumps to page 1
• ACTUAL: The “Jump to page 1” link is not workingQTBUG-131443.zip
