      value: value,
      range: range,
      query: value.text.substring(range.normalizedStart, range.normalizedEnd),
    );
  }

  final end = value.selection.extentOffset;
  var start = end;
  while (start > 0) {
    final previous = TextEditingModel.previousGraphemeBoundary(
      value.text,
      start,
    );
    final grapheme = value.text.substring(previous, start);
    if (grapheme.trim().isEmpty) break;
