    Description

      The attached project (no pun intended) produces the warning,

      Using attached type Test already initialized in a parent scope.: Reference it by id instead:

      Strangeness:

      • Where the "repeated" attachment is made N levels deep, the warning is emitted N times for that line.
      • This warning is not emitted at all if "import QtQuick.Controls.Basic" is removed.
      • This warning is not emitted if our custom attached type is replaced by a "built-in" attached type (like Window.width or Keys.enabled)
