The post asks if it is expected that a feature doesn't work in a WASM notebook. The community members in the comments indicate that the feature is not currently supported, as the interactive backends used (such as WebAgg) rely on technologies like websockets that are difficult to implement in WASM. One community member notes that WebAgg renders plots as raster images, but they are not entirely sure about the details of how it connects. Overall, the comments suggest that the lack of support for the feature in WASM notebooks is expected.
