${name} replacement is not done for popups and done only for feedback "value" field
feedback function tries to invoke sendDrawing function (line 787) if polygon name exists (it shouldn't - throughs exception)
the sample created two buttons demonstrating different behavior (same buttons for popup and contextmenu just for the demonstration on different behavior)
The simple workaround (until I have some time to fix it..), is to avoid sending the shape name in the name field and add it to the value field to be intercepted by the income node handler:
Hi, Attached sample flow demonstrating two issues
feedback(\"*\",{\"attr1\":value1, \"name\":\"{{name}}\"}, action, true);
