When running with AppImage and on Ubuntu I'm getting the error that
QtWebEngine 1.7 is not installed, it seems that per default 1.8 is
installed nowadays.
For some reason in the latest Qt versions the webview took over the
focus from the keyboard, once clicked on the webview the arrow
keys wouldn't register up and thus you couldn't navigate with them
anymore.
This patch fixes this problem by using window.location.href and
checkinf for those special urls. This is way easier to use than
WebChannels.
I have no idea why, I think it might be some timing issues while
initializing the webengine, but when using runJavaScript() in
the WebEngineView without referencing it with the id of that
QML object it just throws the error that it doesn't know what
runJavaScript() is. When we use the ID then it just works
for some reason.
