From the looks of it, this is a race condition - hitting the filters before the grid is loaded. I can recreate this by loading classifications and then as fast as I can hit the "germline" filter button. It takes me about 10 goes

There is only a short window - have to do before "processing" turns up.

It's happened naturally to real users on 2x in 6 months: They were filtering by genes - probably kicked off 2 searches very quickly?

• mybpc3
• gjb2

as rollbar says GET /genes/autocomplete/GeneSymbol/?q=gjb2

Shariant testing required - see reproduction steps above
