UrlAutolinkParser fails for text containing WWW and a subsequent link

[macbookandrew]

For strings containing www followed by a link using [link](https://…) format, the parser mangles the resulting HTML:

<!-- given this string of markdown -->
WWW text followed by a [link](https://example.com/foo-bar-test)

<!-- expected result -->
<p>WWW text followed by a <a href="https://example.com/foo-bar-test">link</a></p>

<!-- actual result -->
<p><a href="https://example.com/foo-bar-test">https://example.com/foo-bar-test</a>tps://example.com/foo-bar-test)</p>
