Fixes #12812 Raise `ActiveRecord::RecordNotDestroyed` when a child marked with `dependent: destroy` can't be destroyed. The following code: ```ruby class Post < ActiveRecord::Base has_many :comments, dependent: :destroy end class Comment < ActiveRecord::Base before_destroy do return false end end post = Post.create!(comments: [Comment.create!]) post.comments = [Comment.create!] ```` would result in a `post` with two `comments`. With this commit, the same code would raise a `RecordNotDestroyed` exception, keeping the `post` with the same `comment`.
