Magento2: Guests can now add to wish list [v2.1.5]

[thdoan]

Preconditions

1. Magento 2.1.5
2. Developer mode

Steps to reproduce

1. Click Wish List button on product page as a guest
2. 
   
   
   3.
   

Expected result

1. You should be redirected to the account login page (at least that's what the behavior was like in v2.1.2)

Actual result

1. After upgrading to v2.1.5, now the guest user is able to add the item to the wish list. I'm not sure if this is a new feature or a bug, but generally guests should not be allowed to add products to the wish list (if this is a new feature, then it should be configurable in Admin). The reason why I think this is likely a bug is because there is a "Sign Out" link in the left nav column, which doesn't make sense for guest users.

It turned out this was a caching issue somewhere in the chain.
