Annotations on diploid / triploid chromosomes

Hi Eric,

I'm trying to display an annotation track on diploid / triploid genomes but I'm having a problem.

The chromosome number seems misinterpreted. For example the annotation of the chromosome 2 appear on the 2nd chromosome displayed by ideogram, which is in reality the 2nd copy of the chromosome 1.

I thought of multiplying the number of chromosomes by 2 for the diploid / by 3 for the triploid etc...

from :
{
        "name": "gene",
        "chr": "5",
        "start": 40489525,
        "stop": 40493890,
    },

to :
{
        "name": "gene",
        "chr": "10",
        "start": 40489525,
        "stop": 40493890,
    },

but that generates an error like below, because the chromosomes number does not correspond to the length anymore.

coordinate-converters.js:13 Uncaught (in promise) Error: Base pair out of range.  bp: 40489525; length of chr10: 37674811

Is there any way to specify the chromosome more precisely? For example like in the range-set table? ploidy: [0, 1, 0]
