Doing a removal of an element inside a QML while using Live Preview does not work.

Mac:
nothing happens - the element stays inside the preview, no warning message

Windows:
a warning message appears inside the editor saying reloading must be done to see this change

Steps to reproduce:

• create a QtQuick application by using the wizard
• start debugging the application (using Desktop target)
• enable "Show application on top" and "Apply changes on Save"
• put a simple Rectangle right before the Text element, I used:

  Rectangle { width: 50; height: 50; x: 100; y: 100; color: "red" }
  

• save file - the red rectangle should appear
• remove this line again and save - nothing happens
