SUMMARY
On my two-monitor configuration, where the primary screen on the right contains a panel with the system tray, system tray applets and tooltips appear mispositioned. Applets appear on the left edge of the screen (when the system tray is on the right), tooltips appear either on the left edge, or on the right side of the screen adjacent to it on the left. 

This is a 5.24 regression; on 5.23.x placement was fine.

STEPS TO REPRODUCE
1.  Set screen panel configuration as follows: two screens, primary screen on the right, panel with systray on the right screen.
2. Hover over a system tray icon, or click on an icon to open a system tray applet.

OBSERVED RESULT
See screenshots: System tray applets open on the left edge of the primary screen; hover tooltips open either on the left edge of the primary screen, or on the right edge of the screen left to it.

EXPECTED RESULT
System tray applets and tooltips should open where the respective system tray icon is.
