[orca-list] a page that lets orca confused

[José Vilmar Estácio de Souza <vilmar informal com br>]

        Hi all.
To reproduce try:
1. Launch firefox 24, I don't know if it happens with other version of FF.

        2. Access https://gist.github.com/joseph-montanez/1948929

3. After the page is loaded press tab until orca reads something like:
'embed this gist'.

4. Press tab again.

At least in my machine orca stays completely crazy. It repeats clone 
this gist, embed this gist, select, unselect ...

Thanks.
