A Javascript appears in the Firebug console when adding a linked review to an existing one.

However it does not seem to impact the user, as it is neither visible in the UI nor preventing the review to be added (nor it prevents to the popup with the review description to be shown).

After quickly checking it, it seems to be a bug in JQuery's autocomplete plugin. Would be good to have some JS expert looks at it.

(see attached screen capture).
