Show Genomic Sites Errors Out (GB Issue I think)

[jpfisher72]

Seems like error is coming from genome browser. Super weird in the way that it errors. To Reproduce:

1. (I think) search any TF. CTCF consistently errors
2. Motif Enrichment Tab
3. On the motif tiles go down the list clicking and closing each "Show Genomic Sites" and then back up, like 1, 2, 3, 2, 1. On chrome it'll consistently error the second time tile 2 is clicked. On firefox it errors out on the second time tile 1 is clicked.
