<input foo=a{1} />

{
  "start": 11,
  "end": 13,
  "type": "Text",
  "raw": "a",
  "data": "a"
}      

Expected "end": 12

Correction this happens on every attribute value that has mustache tags, so even style="color:{color};" has wrong end position for the first Text node

The AST for this should be fixed in 3.40.0.
