An element only pays attention to its most recent ancestor with a
template.  Any ancestors further up the chain are completely ignored.

Something to note is that this should apply even if an element
specifies a position that's not in its template ancestor's template,
but *is* in a previous ancestor's template.  That is, if you swapped
the two template for body and #content in your example, so body had
slots abcd and content had only slots ab, then .news and .sports would
flow into the @ slot, as their template ancestor doesn't have slots
named "c" or "d" (even though <body> does).
