Copy text from "bubbles" on Credits page

When creating a book (or in some cases when translating a “shell”) it would be very useful to be able to copy information from the information bubbles attached to the editable text boxes. If this were possible, regional customizers could add information required for certain categories of books in that region, and it would be at hand when creating books rather than the user needing to copy/paste from another document.

I can do this on a normal book page but not on the credits or title pages.

Hurray! I can now copy/paste text from the bubbles on the credits page. Thank you!
