Leading spaces are not being trimed on the Publisher & Identifiers field.

[T-prog3]

Describe the bug/problem I did just notice that space characters at the beginning of the Publisher field are not being trimmed when you save. This creates an issue where you can have MyBookPublisher and MyBookPublisher if you don't notice the space yourself.

This issue affects both Identifiers fields as well but here you also have the additional problem of ending spaces not being removed. All other fields works as the should.
