<summary> elements are not rendered

[sudoforge]

Description

<summary> elements within a <details> tree are not rendered. This is mentioned in #140, but that seems to be much more focused on whitespace rendering, and I thought it would be useful to have this be in its own, more discoverable, more succinct issue.

Source Code

<details>
<summary>Some summary foo</summary>

Some content bar
</details>

With anything that renders HTML, you get:

Some summary foo

Some content bar

Expected behavior

  **Some summary foo**
  Some content bar

Actual behavior

With glamour (at least, with v0.6.0 used in glow v1.5.1), you get:

➜ glow z


  Some content bar
