Thanks Ryan, feel free to remove any other angular shortcuts you find, I personally never use vendor shortcuts, I wish I had the time to strip them all. Thanks again :)

Question.. how do I get this update into my local code. Thanks!

[Anthropic]

@JamesKellyBluedrop for now you'd have to copy the code change, I will try to make time to do a bump release within the next week to npm.

Thanks for getting back to me :) I did copy the change in for now and things are working again
