Hi there,

I noticed the mouseover text for CRISPR guides on hg38 no longer appear on hover.
I checked on multiple browsers and this problem still persists.
When I inspected the page source, the <area> elements for CRISPR guides are missing the 'data-tooltip' and 'mouseovertext' attributes that other tracks have.
I'm not sure what's going wrong, but hopefully this helps!

Thanks,
Connor
