The Opera Desktop Team reports:

Data URIs are allowed to run scripts that manipulate pages from the site that directly opened them. In some cases, the opening site is not correctly detected. In these cases, Data URIs may erroneously be able to run scripts so that they interact with sites that did not directly cause them to be opened.
