QWebEngineView in a QDockWidget fails to render when floating state changes while runtime
I use a QWebEngineView inside of a QDockWidget on a desktop application on Windows.
After starting the application everything looks as expected, doesn't matter, if the initial state of the dock widget is floating or not. When I change now the state while dragging the widget I get the following error message:
composeAndFlush: makeCurrent() failed
and the content of the QWebEngineView is not rendered. When I move the widget back, so that it gets its origin state, it renders as expected.
I hadn't this issue on 5.8, but on 5.11.
