Thread:Project:Support desk/prop=extracts is only returning the first extract?

I would like to use the API to return the extract from multiple wikipedia articles at once. I am trying, for example, the following:

http://en.wikipedia.org/w/api.php?format=xml&action=query&pageids=3258248|11524059&prop=extracts

But it only contains the extract for the first pageid, and not the second. Other properties seem not to have this limitation. For example

http://en.wikipedia.org/w/api.php?format=xml&action=query&pageids=3258248|11524059&prop=categories

Will return the categories for both pageids. Is this a bug, or am I missing something?

Thanks! Ian
