SUMMARY
If a second panel on the same edge exists, and it is wider, a pop-up from the slimmer panel is impossible to have adjacent to the clicked widget. It always, unnecessarily, honors the width of the wider panel. This is a small encumbrance, but during a workday the extra mousing (and the additional required precision of the movement) becomes annoying.

For a use case, see image. The wide window list is always visible, the slim panel auto-hides; it is used far less frequently.

STEPS TO REPRODUCE
1. Place two vertical Panels on the same screen edge, one markedly wider than the other,
2. Add widgets that open pop-ups in the slimmer panel,
3. Click one of the widgets.

OBSERVED RESULT
The pop-up's location is not adjacent to the clicked widget, but follows the width of the wider panel.

EXPECTED RESULT
Pop-up as close to widget click as possible without covering its panel.

Cannot reproduce on Wayland. Of course Wayland currently suffers from Bug 477939 which impairs this use case in a worse way.

Activate any tray applet popup when shown

This mimicks the same code of the CompactApplet in
Plasma Desktop, and it avoids system tray elements
not having focus when opened in certain situations.

Consider AppletPopups to be SpecialWindows

This allows AppletPopups to be drawn in exclusive areas,
which is required in X11 when having multiple panels on the
same side of different thicknesses.
