Description

amp-analytics not setting cookies when using self-hosted runtime

Reproduction Steps

Observed Behavior:

amp-analytics blocks setting cookies when using a self-hosted runtime.

1. Go to https://www.bedbathandbeyond.com/amp/wm-optimized/store/s/shower

2. Observe self-hosted runtime tag

3. 

4. Observe that "current == proxy" when using self-hosted runtime and checkOriginForSettingCookie() throws error.

5. 

6. Cookie setting error then leads to a cascade of linker tracking errors and malformed beacons.

7. 

Expected Behavior:

amp-analytics sets cookies to track user journey. The page below is not using self-hosted runtime. Cookies work as expected with linker configurations and _ga cookie tracking.
