Falkon & Zoom links

[Juraj Oravec]

Hello,

I am unable to reproduce the mentioned error on my setup.
But I remember similar bug,
https://bugs.kde.org/show_bug.cgi?id=494222

The issue was that when Falkon was configured in the system to open 
protocol it cannot handle, it would (by qtwebengine) push this on the 
operating system (without asking), which would in return try to open 
another Falkon tab/window.

A possible solution is to ask what to do with unknown protocols. Looking 
at the code, this feature was there with webkit and not available with 
webengine. I wonder if there is a way to bring it back.

Best regards,
Juraj
