What specific section or headline is this issue about?

Dragging Nodes

What information was incorrect, unhelpful, or incomplete?

Nodes and elements in a document may be dragged using the application/x-moz-node type.
I test with this script:	var dt=new DataTransfer() dt.setData('application/x-moz-node',document.documentElement) dt.getData('application/x-moz-node')//this line will be the output
results:
where?	output
chromium 108.0.5359.95 normal web page	'[object HTMLHtmlElement]'
librewolf 107.0.1-2 (firefox fork) normal web page	error: DOMException: The operation is insecure.
librewolf 107.0.1-2 (firefox fork) about:addons	"[object HTMLHtmlElement]"
There was error or node got stringified.

• firefox specific (because moz)
• setting application/x-moz-node doesn't work in firefox:
  • dt.setData('application/x-moz-node','put anything here') throws DOMException: The operation is insecure. in firefox
• and application/x-moz-node doesn't exist by default:
  • dt.getData('application/x-moz-node') always returns empty string
  • (yes, I tried with draggable html element in drop event)

mdn page:

Nodes and elements in a document may be dragged using the application/x-moz-node type. The data for the type should be a DOM node. This allows the drop target to receive the actual node where the drag was started from. Note that callers from a different domain will not be able to access the node even when it has been dropped.
