The Parser test "External links: wiki links within external link" says:

!! test
External links: wiki links within external link (Bug 3695)
!! input
[http://example.com [[wikilink]] embedded in ext link]
!! result
<p><a href="http://example.com" class="external text" title="http://example.com" rel="nofollow"></a><a href="/index.php?title=Wikilink&amp;action=edit&amp;redlink=1" class="new" title="Wikilink (page does not exist)">wikilink</a><a href="http://example.com" class="external text" title="http://example.com" rel="nofollow"> embedded in ext link</a>
</p>
!! end

but the parser produce:
!! result
<p><a href="http://example.com" class="external text" title="http://example.com" rel="nofollow"></a><a href="/w/index.php?title=Wikilink&amp;action=edit&amp;redlink=1" class="new" title="Wikilink (Seite nicht vorhanden)">wikilink</a> embedded in ext link</p>
!! end

The description after the wikilink is not linked to the external page, who is specified by the test.
