Annotate widget crashes after generating results

[DLWheeler]

After providing t-SNE 'Data" as 'Reference data" and a list of marker genes as "Genes" to the Annotator widget, it correctly generates the annotation graphic and gives the progress as 100% but then continues to run (run indicator continues to circle) and stalls the workflow. Using the basic example given in the help for the Annotator widget will generate the stall. The error log gives:
