Office 365 web apps and Office and SharePoint Add-ins Validation Test Results July 14, 2017:

"Your visual does not appear to filter outwards to other visuals. If this is by design, you may disregard this fail. On subsequent submissions if there are no other failures then we will approve this visual."

Related: When a filter outside of the timeline storyteller is applied, colors revert back to whatever the tool automatically generates instead of retaining custom color selections.
