The <!DOCTYPE> prototype is DocumentTypePrototype and a regular element is ElementPrototype.

For example a <div> is ElementPrototype > HTMLElementPrototype > HTMLDivElementPrototype.

So if you're hydrating at the top level of the document, you need to account for this since you can't create <!DOCTYPE html> like a regular element.

Creating regular html element in JS 
document.createElement("div");
Creating !DOCTYPE in JS 
document.implementation.createDocumentType('html', '-//W3C//DTD XHTML 1.0 Transitional//EN', 'http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtdd');

There's a discussion with more details regarding the challenges of hydrating <!DOCTYPE> in Svelte here: plentico/plenti#91
