Holding down arrow key to navigate breaks navigation

[jphager2]

Navigation through the moves of a game breaks when you hold down the arrow buttons for a while.

To reproduce just hold down the right or left arrow key. After several moves the navigation breaks, and you need to refresh the page to fix.

Probably pretty low priority since there is an easy and obvious workaround. But still would be nice :D.

There is a backtrace:
