Destroying Android QML WebView element does not destroy (leaks) native webview itself

I have attached example app to reproduce issue.

Problem is, that even if WebView.Component.onDestruction is called (you can see console.log output noting that), console.log() output from Chromium itself is still going on (you can see "ping" every one second).

Even so, if you create/destroy WebView multiple times in app provided, you can see that "pings" multiply, meaning that every WebView creation creates native web view but does not destroy it.
