P1: Critical Description
Qt application crash when user press Ctrl+C on selected text on page loaded via QWebEngineView object.
Copy to clipboard by component context menu works fine, but I guess this is implemented by QtWebEngineProcess.exe side
Step to reproduce:
1. Create new Desktop application project
2. Create and load any page by QWebEngineView object
3. select any text on page content
4. Press Ctrl+C
5. Watch how nicely Qt crashes
