Is it documented anywhere that when a Custom Record is created with a Parent-Child relationship and the field on which the relationship is created is set to the Multiple Select type with a Parent Record value that a inline editable sublist no longer appears on the parent record when creating a new instance? I realize the Allow Child Record editing option needs to be enabled on the Custom Record an that the documentation states that if the Parent has more than 10K child records then the option is ignored. But it appears it also ignores it if the type is set to Multiple Select as opposed to List/Record.
