It is not a bug, it is a feature.
It is implemented that way for historical reasons, long ago by someone
at the CS lab. It can't be changed now, because there is code that depends
on the old behaviour, for instance, the distribution in the emulator itself
and dets (including dets files).
We have actually made an attempt to fix this "bug", but failed miserably
because too much code depended on it.
