Right click to bring up menu on icon in task manager and icon-only task manager on second monitor, menu appears on the lower right corner of first monitor.
Only happens with task manager and icon-only task manager.

I chose task manager for component in the bug report - even though it also happens in icon-only task manager (shown in the video).

Reproducible: Always

Steps to Reproduce:
1. Setup a panel at the left side, of the right-and-below monitor. (See video.)
2. Right click an icon in task manager/icon-only task manager in the panel you setup in (1).


Actual Results:  
Menu appears on the wrong monitor, in the lower-right corner nearest to the right monitor.

Expected Results:  
Menu should appear near the mouse to the right of the (left-aligned) panel.
