Display PDF in 5.15

[RayL]

I was using Qt 5.14 Webengine to display PDF files fine. Then I upgraded to Qt5.15 and PDF files are not displaying anymore (show empty gray screen).
I did a quick test. I ran the Qt Example quicknanobrowser with Qt5.14 and it displayed a local PDF file fine. Then I ran the same exmaple with Qt5.15 and I got an empty gray screeen.
Am I or Qt 5.15 missing anything?

The embedded PDF viewer in qtwebengine is non-functional. Fixed for 5.15.1.
