SUMMARY
When using multiple lines in the task manager, if a window group resides in a lower row, the previews of the grouped windows are replaced by the previews of the window(s) above when moving the mouse up, making it impossible to select one of them. The task group has to be ungrouped or moved to the top row first to select individual windows.

STEPS TO REPRODUCE
1. Configure Task Manager: set maximum rows >= 2
2. Start several programs to start filling the Task Manager's second row.
3. Create several instances of a program and group it in the Task Manager.
4. Move the task group to the second row.
5. Hover over this group, wait for the preview to appear.
6. Move mouse up and try to select one of the grouped windows.


OBSERVED RESULT
Preview is quickly replaced with preview of task(s) above and click selects window of this task instead.


EXPECTED RESULT
Preview should remain long enough to be selectable by mouse
