Because the following judgment is options.copyStyles !== false, so if it is not passed, it is also executed in accordance with true.

In fact, we just have a difference about what is the true . It will execute correctly under the strict-Boolean-type. The options.copyStyles !== false is a strict un-equality which likes ===.But, the serializeImages condition in line 209 is not strict which likes ==.So, In my option, we should keep the same style about the serializeImages and copyStyle condition what are both the Boolean value through the docs on the one hand, on the other hand, It should excute false statement when the value is either '', or ``, or null,or undefined,or NAN. All above these just beacuse JS is a fuck weak type language😓.
