Fixed
- The panel opens on the right monitor. With the taskbar on several monitors, a group on another monitor's taskbar opened its panel in the corner of the main one. It now opens over the icon you clicked, on that screen. The same goes for open on hover and for groups inside a group. On a screen at a different display scale, the panel also opened away from its icon and closed with the cursor still on it; that is gone too. (#7)
- The animation stays on its own screen. The panel that slides out from behind the taskbar showed on the monitor below or beside it on the way. Where there is another screen past the taskbar, it now peeks up instead.
Good to know: on a screen at a different display scale from the main one, Windows stretches the panel, so it can look a little softer there.
Thanks to @the4thb for the clear report.
