Yes, it's a known bug.
https://bugzilla.mozilla.org/show_bug.cgi?id=275689

As a result of that bug, same-document references in documents with 
xml:base or html:base (like documents from the Google cache) don't work. 
Also content-location support is removed in Firefox because it broke 
same-document references (which hadn't be the case if same-document 
references would have been correctly implemented in the first place.)
