<tbody> is missed on rendering doc

[blackst0ne]

I have such a simple markdown with two tables:

| Input       | Expected         | Actual    |
| ----------- | ---------------- | --------- |
| One         | Two              | Three     |

| Header   | Row  | Example |
| :------: | ---: | :------ |
| Foo      | Bar  | Baz     |

I want to render it to a doc and then to a HTML string using the CommonMarker::HtmlRenderer.new.render, but the result gets lost the <tbody> tag of the second table.

require 'commonmarker'

content = File.read('path/to/markdown.md')
doc = CommonMarker.render_doc(content, :DEFAULT, [:autolink, :table, :tagfilter])
CommonMarker::HtmlRenderer.new.render(doc)

In my real case I use my custom renderer inherited from the CommonMarker::HtmlRenderer, but it doesn't matter because the bug is reproducible with the gem's methods.

By the way, if I run either doc.to_html or CommonMarker.render_html(content, :DEFAULT, [:autolink, :table, :tagfilter]), the second <tbody> is added just as expected.
