Sorry if this is an issue with Hugo and not the theme. I'm not sure what's responsible for what.

Describe the bug

By themselves, hyperlinks in headers are functional. But they generate weird ToC entries.

Reproducible example

## Example [hyperlink](https://example.com/) in a header

generates a split-up ToC entry.

The left end takes you to the header (as expected):

The middle part doesn't look like a hyperlink, but it's a separate hyperlink that takes you to an external website:

Finally, the right part doesn't work. It's just nornal text that doesn't take you anywhere:

Expected behavior

Normally, a ToC entry is a one big hyperlink takes you to the header:

This is the most obvious behavior that I can imagine for my reproducer.

Another possible option to keep it "split" but fix the right end (so that it takes you to the header) and underline the middle part (so that it looks like a hyperlink, which it is).
