field.value doesn't use options.defaultValue when it is a function

[glutentag]

Hello,

When field.value is a function, it uses field.default as a default value but doesn't use options.defaultValue.
Also, if the function returns a falsy value, it is replaced by the default value.

It is from this line:

} else if (fieldElement && typeof fieldElement.value === 'function') {
  val = fieldElement.value(dataElement) || fieldElement.default;
}
