SUMMARY
If you click a Web link in the preview window of a message, focus is immediately changed to the Web browser instead of simply opening the link a browser tab in the background.

This is a regression.

I reported this bug here https://bugs.kde.org/show_bug.cgi?id=484481 in March of last year.  That bug was closed as a duplicate of https://bugs.kde.org/show_bug.cgi?id=482568 which was closed in December of last year.  The developer commented that this problem was a different issue in spite of the fact that the original bug was closed as a duplicate.

OK, here's a new bug.  This behavior was changed from years of the original behavior of opening a link in the background.

STEPS TO REPRODUCE
1.  Click link in preview of a message
2. 
3. 

OBSERVED RESULT
Focus changes to browser application.

EXPECTED RESULT
Link should open in background, preserving focus on kmail preview window.
