HTML parser: crashes if table described in one line

[braska]

I've opened https://rexxars.github.io/react-markdown/ and tried to check following snippet and all works fine:

<table>
  <tr>
    <td>1</td>
    <td>a</td>
  </tr>
</table>

But if I am trying to use this one all crashes:

<table><tr><td>1</td><td>a</td></tr></table>

Stack trace from console:

Uncaught TypeError: (el.props.children || []).concat is not a function

Seems to be happening with any one-line HTML string

same question

I can confirm that it throws that error with one-line HTML strings.
Adding a newline fixes it temporarily. Example:

<ReactMarkdown source={`${content}\r\n `} escapeHtml={false} astPlugins={[parseHtml]} />

this will be resolved in #428

This should be solved by landing GH-563 today, which will soon be released in v6.0.0!
