oh noes!
there's no selector{} block
now u can't do anything with <style>
i suggest
"type": "eeeeeeg", "message0": "style of %1 %2 %3", "args0": [ { "type": "field_input", "name": "selector", "text": "selector" }, { "type": "input_dummy" }, { "type": "input_statement", "name": "NAME" } ], "previousStatement": null, "nextStatement": null, "colour": 225, "tooltip": "", "helpUrl": "" }
