Noticed today that on a couple lists where we've added a content editor to the underlying newform.aspx, to run our own JS etc, have stopped automatically loading the classic forms.
It used to be that if SharePoint detected you were using something that didn't work on the modern forms, it would load classic (and this does still happen on some other sites/tenants I've tested).
Are there any official updates on this behaviour?
