Best Practice Recommender - Suggest Popup close action

A common problem i've often seen when building Popup page is that the 'Close Action' configuration gets overlooked when changing a default Cancel button to a microflow action with custom cancel logic.

In these cases the usual behaviour of the popups Close button would be to trigger this custom logic.

if you forget this you often get unexpected application behaviour - and while end-users report that they 'clicked the close button' you not always realize that they might have used the small x button.

To help identify these potential problems an addition to the 'best practice recommender' would be great.

This would check, if a popup doesn't have a standard cancel button and in such cases suggest to set a custom close action.
