Description
Spawned QtWebEngineProcess(es) aren't killed after WebEngineView destruction.
It's a common use-case to use WebEngineView inside Loader and instantiate it only when necessary. This allows do not allocate a huge amount of resources for Chromium and free it when you don't need this anymore.
Loader {
id: loader
active: false // controlled outside
sourceComponent: WebEngineView {

}
}
Please see attached demo application.
At least on Win10 after WebEngineView destored there are still a few of QtWebEngineProcess(es) in the system
