I'm using a Pixelbook Go and I installed the PWA app.

Describe the bug
Each time I click on a square, the PROXX title at the top adds another PROXX to itself. Eventually it fills the entire top of the screen. The problem appeared to happen spontaneously after a few rapid clicks in a row. It's now repeatable with each game.

To Reproduce
Steps to reproduce the behavior:

1. Start playing
2. Click on a square
3. Notice the title PROXX becomes PROXXPROXX.
4. Each time you click, another PROXX is added

Expected behavior
Title should be fixed as PROXX
