Actually, this seems to be a reproducible behaviour. Regardless of where I (single-)click to select a book (or whether I select it via keyboard), whenever I press the delete button, either the title or the field I clicked on to select gets deleted and goes into edit mode. It's never bothered me, but I've noticed it.
