Description: format(input): convert to string before concat
 The checked character for `<input type="checkbox">` was concatenated to
 the '[' and ']' characters before converting it to string, which
 resulted in an expression like '[' + 'X' + ']', which results in an
 arithmetic sum between the integer values of the three characters,
 leading to an unexpected result.
 .
 To fix this, simply wrap the checked ternary expression with a braced
 string constructor.
