Validation error on custom entity child (via dialog) fires same error on main CE field

[ricalebro]

I have a blog CE, and a blog author CE as a property of the blog.

On the 'create' page for the blog, I clicked the + to add an author and got a validation error when creating the author (author title already exists). When I closed that dialog the same error is then showing for the Title field of the blog.

Child-forms don't have unique scope for validate errors, this also happens with the global validation summary.

A workaround is to adjust the value of the invalid field which should remove the validation error.
