Description

The step object can be augmented by the toUIIntegrationStepCollection function, it will have a isUnclosedSplit property that can be used to show the icon (and relative tooltip).

The AddStepPage is already used the augmented collection. The IVP isn't (and it's not even showing the data mapper warning icons).
