When I set Webkit engine as default, in internal browser forward and backward buttons are greyed out and non functional.

Reproducible: Always

Steps to Reproduce:
1. Set Webkit engine as default in Konqueror.
2. Open an article as webpage in tab.
3. Click a link


Actual Results:  
Backward button stays grayed out.

Expected Results:  
Backward button becomes clickable just as with KHTML.

I use Akregator 4.14.2, but happen with earlier versions as well.

I´d like to use Akregator with Webkit, cause it displays pages better and with KHTML its gets slower and slower on tab close at least when browsing articles from some newsfeeds. Up to the point it becomes unusable, hogging a core for a long time.
