The bug
As the title suggests, when you click the sign book page in a book and quill, the next page arrow is visible.
Also if clicked it will play the sound and stay orange even when the mouse is moved off of it.

That's a similar issue, but that's not the same bug right? That's talking about not being able to edit a book when the arrow is clicked. This is about the arrow being there in the first place.
