I think what happens here is that step 4 will add Nytimes into the allow list (can check it in chrome://settings/content/javascript), so we won't use the default shields rule but its own rule.
It seems like an expected behavior to me that the rule of a specific site has higher precedence than the default shields rule. cc @bbondy

@yrliou That's correct. I am seeing nytimes in Allow list under chrome://settings/content/javascript

As per the above comment, it's expected behavior. Hence closing the issue.
