Tippyjs: The undefined props are not set to defaults

[makarov906]

Bug description

If pass the undefined option, then tippy will use this value instead of setting the default value

Reproduction

tippy('button', {
  content: 'tooltip',
  trigger: undefined
});

`Uncaught TypeError: Cannot read property 'split' of undefined`

That's how object spreading works, { ...defaults, ...specified}, the undefined value takes over the default. How should it work?

[makarov906]

I expect defaults options to be applied

[atomiks]

Hmm yeah I guess.

Why has this been closed? I think this is a valid bug. I was just creating a wrapper component for this and had to manually remove all undefined props before passing them to tippy. I agree with @makarov906 that default values should be applied.
