Inference rule missing for num_tiles_in_slice_minus1?

Description

Should there be some form of inference rule for num_tiles_in_slice_minus1? Currently it is only signalled when rect_slice_flag is 0 and NumTilesInPic is greater than 1. As far as I can tell, it seems to be used only when rect_slice_flag is equal to 0, so there does not seem to be any reason to infer it when rect_slice_flag is equal to 1.
However, what about the case when rect_slice_flag is 0 and NumTilesInPic is equal to 1? Please note that this is really a corner case, since it corresponds to a picture with only one tile and one slice (i.e. no partitioning), but for which no_pic_partition_flag would be equal to 0. While this corner case does not really seem to make sense, it does not seem to be prohibited either.
Any comments?
