Description
Upgrading from 5.24 to 6.0 results in the customdata prop missing when iterating over click/selected data of a go.Scatter trace. This happens within a Dash app callback with clickData and selectedData as inputs.

Research direction
Start by reproducing the Dash callback behavior described in the issue with a go.Scatter trace, clickData, and selectedData, comparing versions 5.24 and 6.0. Trace where customdata is lost during iteration; done when customdata is available in the callback data after upgrading to 6.0 or the regression is otherwise resolved.
