@dustine32 @tmushayahama Also noting that the work should be done in the new repo https://github.com/geneontology/web-components (see: geneontology/noctua#1029). (This should also make iterating and testing easier.)

@kltm Ahh, ok! I can just move this ticket to https://github.com/geneontology/web-components.
