not on the new document but on our viewport item

Maybe we should set this to true on crash as well.

I dont think the comment is needed

same here

>      _q_viewportUpdated();

I hate callbacks like this here... have to look what it does... not your fault though :-) and not part of this patch

A comment here would make sense, linking to the wiki page for instance

> Source/WebKit2/UIProcess/API/qt/qquickwebview_p.h:97
> +            p->interactionEngine->applyConstraints(p->computeViewportConstraints());

future: Maybe those constraints shouldnt be in the interaction engine itself

> Source/WebKit2/UIProcess/API/qt/qquickwebview_p.h:111
> +    bool isTransitioningToNewPage() const {return transitioningToNewPage; }

missing space

> Source/WebKit2/UIProcess/qt/ClientImpl.cpp:157
> +    if (!WKFrameIsMainFrame(frame))
> +        return;

I prefer a newline after this
