What is Expected?

Both should render correct sentence.

What is actually happening?

The first one parses line break as a VNode

<i18n path="msg" tag="div">
  <strong>bold</strong>
  <em>italic</em>
</i18n>

So that the second slot in i18n string was replaced with the TextNode, which was the line break between two child elements.

I have to now write it like this.

<i18n path="msg" tag="div">
  <strong>bold</strong><em>italic</em>
</i18n>

I'm not sure whether this should be dealt with by vdom or by i18n lib, I prefer the latter. Nonetheless, for this particular functional component, I think only element nodes (nodeType === 1) should be considered. Since plain text can be easily moved to i18n message object.
