this is wrong. It must return a boolean

I writed this because if the element is not a select tag, It is not logical to return a boolean. That would be nice if I throw an exception instead of return null? Or editing the documentation of method to @return Boolean|null?

IMO it's better to throw an exception.

You can safely inline this variable, because it's used only once.

return $optionElement !== null;
