Active alignment length off by one in "Supplementary alignments" read information

[ASLeonard]

I feel like I've seen an issue/fix about this mentioned before, but couldn't find the issue.

This is using igv on mac v2.19.5

When looking at 3 split alignments, the clicked on alignment (bolded) is one basepair longer than the same alignment when clicking on the other reads. This happened for all 3 split alignments, where the non-active alignment lengths agreed between the other 2 (and match the reference-span).
