Bug 455774

Opening links with an application which has a window already open doesn't work well like in X11:
- If the opened window is on the same virtual desktop, it won't change focus (1)
- If the opened window is on another virtual desktop, the highlighted task manager icon won't appear (2) or it will be broken (clicking on it won't change focus to that window) (3)

STEPS TO REPRODUCE (1)
1. Open an application (like a browser)
2. Open another application on the same virtual desktop
3. Open a link in the second app with the first app

OBSERVED RESULT (1)
Focus doesn't change to the first application when the link is opened

EXPECTED RESULT (1)
Focus changes to the first application when the link is opened


STEPS TO REPRODUCE (2)
1. Open an application (like a browser)
2. Open another application on a different virtual desktop
3. Open a link in the second app with the first app

OBSERVED RESULT (2)
The highlighted icon of the first app doesn't appear

EXPECTED RESULT (2)
An highlighted icon of the first app should appear in the task manager.
Clicking on this icon should change focus to the first app (where the link is opened)


STEPS TO REPRODUCE (3)
1. Open an application (like a browser)
2. Open another application on a different virtual desktop (like Konsole)
3. Open a link in the second app with the first app using the  "Search << >> with"  function

OBSERVED RESULT (3)
An highlighted icon of the first app appears in the task manager, but clicking on it doesn't change focus to the first app

EXPECTED RESULT (3)
An highlighted icon of the first app should appear in the task manager.
Clicking on this icon should change focus to the first app (where the link is opened)
