Allow to use DocumentFragment as content value

[sqal]

Problem

const content = document.createDocumentFragment();

// ... create some template
//  content.appendChild(item1)
//  content.appendChild(item2)

tippy.setContent(content)

Right now it's only possible to use string or HTMLElement as content value. Setting DocumentFragment as content doesn't work and we'll see [object DocumentFragment] instead of our HTML template.

Solution

Current solution is to wrap our content in div element instead of fragment.

What's wrong with using a wrapping div tag? Generally fragments are useful to keep markup correct but in this context it doesn't matter, since the parent is just a div.
