when you are writing a book and notice you made an error at the beginning of a page, you have to delete the whole thing in order to undo the error. the same goes for not being able to copy and paste. although I know this was never added, the reason I added this as a bug is because it's strange that you can move your cursor in all the other ingame-interfaces like: anvils, chat, command blocks, seed, name-world, flatworld costumization but not in books

what I expected to happen was: I click with my mous or move with my arrow buttons in front of the word to undo my error.

what actually happened: I had to delete the whole thing in order to undo the mistake.

steps to reproduce:

1. write a page in a book and quill

2. try to go back to the first sentence without deleting everything you wrote.
