    - This cl will not include the animation when taskbar variant is changing between launcher and desktop mode.

Solution
    - if desktop tasks are visible we will open any app from taskbar context into Desktop windowing mode after launching the DesktopTaskView manually. We will launch desktop task from recentview first and upon end of recent animation we will launch the app.
