Polyfill error?

[Esteban-Rocha]

Hi! I'm getting this on the console on every single site, even if it does not have a form on it.

Chrome - Linux
Version 65.0.3325.51 (Official Build) dev (64-bit)

Any ideas? I did not have those yesterday, maybe an update break something.

Thanks! Regards

i've seen this error before too, i'm not sure if it's anything serious. i'll try and look into it further.
