Prettier 1.15.2
Playground link

--parser angular

Input:

<pre><code #foo></code></pre>

Output:

<pre><code #foo></code>></pre>

Expected behavior:
Prettier should not add an extra closing angle bracket after </code>

EDIT: changed example to use <code> instead of <p>. This is how I originally found the bug, not sure why I thought it would be better to replace <code> with <p>...
