We want the notifications in the flyout to behave just like links,
including standard middle-click and Ctrl-click behavior. The simplest
way to do that would be to actually make them links - but the area can
contain a few other links, so we can't do that and have to resort to
ugly hacks.
Or do we?
Turns out that while browsers won't accept HTML containing nested <a>
tags[1], such a structure is valid XHTML, and it's possible to create
such structure in HTML mode using DOM manipulation. It works like one
would expect: the entire thing is clickable, but inner <a> tags' hrefs
override outer ones.
Firefox even had a request to make that work[2] which was happily
fulfilled.
Tested the basic case [see below] on Firefox 22, Opera 12, Opera 15
(which uses the Blink engine like Chrome), IE 8 and IE 6 and it works
the same on all of them. Tested the XHTML variant [see below] on all
of the above except for the IEs which don't grok XHTML and it exhibits
the same behavior.
[1] Simple test: $('<div>1<a>2<a>3</a>4</a>5</div>').html() is
"1<a>2</a><a>3</a>45", not actually "1<a>2<a>3</a>4</a>5" like one
might expect.

The test cases used are below. When trying out the XHTML one make sure
that the browser uses application/xhtml+xml MIME type; saving the file
with .xhtml extension should be enough.
XHTML:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<body>
<div>1<a href="http://google.com/">2<a href="http://example.com/">3</a>4</a>5</div>
</body>
</html>
HTML:
<!DOCTYPE html>
<html>
<body>
<script type="text/javascript">
var div = document.createElement('div');
var a1 = document.createElement('a');
a1.href = "http://google.com/";
var a2 = document.createElement('a');
a2.href = "http://example.com/";
div.appendChild( document.createTextNode('1') );
div.appendChild( a1 );
a1.appendChild( document.createTextNode('2') );
a1.appendChild( a2 );
a2.appendChild( document.createTextNode('3') );
a1.appendChild( document.createTextNode('4') );
div.appendChild( document.createTextNode('5') );
document.body.appendChild(div);
</script>
</body>
</html>
