It is not a bug - and neither a feature. It is simply a limitation from the
design. Originally feature request supported: 1. no filter, 2. filter by
rect, 3. filter by fid. Those options were used in mutually exclusive way
so there was no reason to make the code more complex and allow their
combinations. Now with more filtering options this would be useful - maybe
in the future someone will find time and implement support for multiple
filters at once....
