inline code is stripped, even with --no-stripHeadingTags

[trusktr]

Input:

## The `<log-in>` element

Expected output:

  * [The `<log-in>` element](#the-log-in-element)

Actual output:

  * [The `` element](#the-log-in-element)

---

Without the --no-stripHeadingTags option, the tag is still erroneously treated as an HTML tag:

With the same input, the actual output is:

  * [The `` element](#the--element)
