QuickDesigner: Clicking into property text field does not remove focus from preview

Steps to reproduce:

• create Quick Controls app from template
• switch with qml file to Designer
• drag a TextInput onto the preview
• double click into the TextInput (inside the preview) as if you want to enter the text
• click now into the Text property of the TextInput
• change the text there
  • hitting Enter or giving some other property the focus does not update the preview
  • clicking onto the preview (outside of the TextInput) removes the input thingy from the TextInput, and updates the "modified" property to the old value
