Parcel: Cannot get element after self-closing Vue component

[nyaapass]

🐛 bug report

After upgrade to parcel-bundler 1.10.0

If there are something after a self-closing vue component like:

<button>    
  <slot />
  <span>You can't see me!</span>
</button>

You will see no <span> after <slot> content.

But if you change it to:

<button>    
  <slot></slot>
  <span>You can see me!</span>
</button>

The <span> will be seen.

But when I was using v1.9.7, everything was okay. (Here is a demo branch using v1.9.7)

It seems like some changes in v1.10.0 caused this problem.
