WebCat mock_front branch prod build is not loading on Mac Safari

[tareq89]

Background:

WebCat mock_front branch prod build is not loading on Mac Safari. The error it is giving is:

1. TypeError: Attempting to change configurable attribute of unconfigurable property
2. reflect-metadata shim is required when using class decorators

I found this stackoverflow question where it is mentioned to add reflect-metadata, es6-shim and zone.js in the index.html file. Though in our production build, all these files should be bundled up, I added these js files on production build's index.html locally (except zone.js, adding it was showing zone.js is already loaded in the bundle.js). Then tried to load it on chrome, firefox and safari.

In safari, it is now giving another error telling,

Cannot resolve all parameters for 'b'(a @Optional(), [object WindowConstructor], [object DocumentConstructor]). Make sure that all the parameters are decorated with Inject or have valid type annotations and that 'b' is decorated with Injectable.
