Describe the issue
Keywords, such as static_assert, sizeof, etc. are typically followed by parentheses. static_assert; will be highlighted as if it's a keyword, but static_assert(true); is highlighted as a built_in.

Which language seems to have the issue?

<code class="hljs cpp">
<code class="hljs c++">

Are you using highlight or highlightAuto?

highlight, I think?

Sample Code to Reproduce

In reveal.js, with a freshly-downloaded hljs, add the following:

<pre><code class="hljs c++" data-trim data-noescape data-line-numbers style="overflow: visible;">
  static_assert; // highlighted as keyword
  static_assert(true); // highlighted as built_in
</code></pre>

Expected behavior

Keywords continue to use their keyword colour when followed by parens.
