Planned design for this:
Clicking on the high score on the game over screen flashes the score. During that time you can tap again to reset. The flashing stops out after 6 times.

Able to reproduce this issue on Windows 10, Mac OS 10.14.0 and Ubuntu 17.10 on the reported version 72.0.3625.0 and the issue is fixed on the latest M-73 build 73.0.3646.0.

1. Launched Chrome 
2. Opened dino game
3. Started playing and clicked on high score when game over> observed blinking and while blinking clicked on high score > observed score is rested 
Attached is the screen cast for reference.

Hence adding TE verified labels as the fix is working as expected.

Thanks..!
