[Bug 990496] [NEW] sorting of windows is upside down after private mode

[LAZA]

Public bug reported:

i have some windows opened up and change sometime into the private mode
--> all windows on the taskbar where closed and a new (in private modus) opened up

after leaving the private mode by clicking again onto it the windows in the 'normal' mode come back and are opened up.
but the sortation on the taskbar is now reverse.

Example:
- starting firefox, open windows:  A, B, C
- changing into private mode, open window: Z
- leaving private mode, opens up again: C, B, A
