Just a question: Javascript error angular.js? Is this normal or is knockout being replaced by angular? (which i would totally like)

[VZeroCool]

@johnny-longneck Its angular.js error I think..

@VZeroCool : this was already reported for Magento 2.2.4 and was already fixed in #15211, it was badly communicated and was not fixed in 2.2.5, but should be fixed in 2.2.6

I can confirm that the same fix if applied into Magento 2.2.5 it will work. Thanks to all community member about that.
