QWebEngineView memory leak

Creating and deleting a QWebEngineView appears to create a memory leak. I have tried the attached code on 5.9, 5.10, and 5.11 and see the same memory leak on each.

I do not have a valgrind result to attach as I've had difficulty capturing that data.

To reproduce:

• Build this application
• Run the application ./leak-test
• - While application is running:
•       while true; do sleep 1; grep VmRSS /proc/$(pidof leak-test)/status | awk '{print $2}'; done
• - Observe, or graph, that these values are increasing over time
