PlasmaShell overlays render with erroneously large vertical margins

To demonstrate: [1]

This is present without the “noborderrule=2.kwinrules rule active, too. I’ve solely enabled it for that screenshot, because it is required for spectacle to identify the window, as is also true for the undermentioned:

  1. #!/usr/bin/env sh
    qdbus-qt6 org.kde.KWin /KWin org.kde.KWin.queryWindowInfo
    
  2. activities: caption: plasmashell
