Error in console slows down browser

[nick-keller]

When scrolling stops you can see an error in the console:

Uncaught TypeError: Converting circular structure to JSON

This can be seen even in the exemple here: https://react-window.now.sh/#/examples/list/fixed-size

On complexe list it even takes a while for the user to be able to interact again, interaction is disabled until the error pops in the console.

Sounds like you're trying to console.log a JSON structure that has circular references somewhere in your application.

This can be seen even in the exemple here: https://react-window.now.sh/#/examples/list/fixed-size

Sorry, but no such error shows in the console on the demo site.

On complexe list it even takes a while for the user to be able to interact again, interaction is disabled until the error pops in the console.

See the reason for the interaction bit here: #128 (comment)
