Backspacing does not erase previous letter

As stated above, the problem with backspacing is that it no longer erases the last letter, but instead moves the line back by one, effectively restricting the player from removing the "New World" text.

Steps to reproduce bug:

1. Open the app entitled "Minecraft PE" (no quotes) in version 0.13.0 Alpha. If the enlisted version in the bottom left corner does not match, update the app.

2. Select the "Play" icon laid out point-blank in the middle of the screen, and directly in front of your face. You can't possibly miss it.

3. Select the "New" icon in the top right corner of the screen. Attempt to edit the name of the world.

4. Press backspace.

A new update repairing this bug would be much obliged.
