But, when I query my annotation server, it actually returns the
'correct' result: it says there is a feature in this region which
overlaps the actual view area. Because the features are so large they
are in chromosomal coordinates. Ensembl takes it upon itself to throw
away the result. If the annotation server does not return a result I
could understand it, but that is not the case.

So I would classify it as a bug in Ensembl: the annotation server
reports a result, the viewer decides that it is not a real hit...

Nope, if the begin and end-point are outside the view region it does
not display. Just go the website and try some extended features.
