Webclient patches

#### Mouse scrolling not properly prevented
With recent chrome/firefox versions, page is still scrolled and console is spammed with\
```"[Intervention] Unable to preventDefault inside passive event listener due to target being treated as passive."```

You need to to register events as a passive handler. Look for something like:
```
eventHandler.target.addEventListener(eventHandler.eventTypeString, jsEventHandler, eventHandler.useCapture);
```
and change to 
```
eventHandler.target.addEventListener(eventHandler.eventTypeString, jsEventHandler, { useCapture: eventHandler.useCapture, passive: false });
```
