Breakout AI has phantom tile issues

[christopolise]

Describe the bug
After watching the breakout_ai demo for a while, I have noticed that on occasion, the ball will hit an invisible brick and redirect.

To Reproduce
Steps to reproduce the behavior:

1. Run python main.py -vvvvv demos breakout_ai -s
2. Wait and watch, the phantom hits tend to be more noticeable when there are less bricks to clear

Expected behavior
We should not have any phantom bricks 🤷‍♂️
