Author sort tweak on adding

Hi,

I have the tweak author_sort_copy_method set to 'copy' which should copy author to author_sort without modification.

Now I noticed that upon adding some books from Standard Ebooks, I'm getting the author_sort set as LN, FN. So I need to select the books and correct that by running the Bulk Metadata edit function "Automatically set author sort".

Is this how it has always worked, or am I missing something? I think the 'copy' tweak used to work for newly added books, but I'm not sure.
