Suggested usability change when editing Marriage section of a person's entry

Suppose a person already has a Marriage entry which has a start date but no end date and just the "Present" box ticked (because the marriage is ongoing). If that person dies, you add the end date as being the person's date of death. But if you forget to untick the "Present" box, that date is ignored. (see 250604-083709-447000 and re-submission 250604-084024-881000) How about changing the form-validation logic so if the end date day/month/year fields are populated rather than being blank, the "Present" flag is automatically unticked - or at least generate a warning to remind the submitter to do it manually?
