Clicking links in the left-hand pane of any AWS documentation (e.g. https://docs.aws.amazon.com/AmazonS3/latest/API/Welcome.html) causes the following console error (from Ka-Block):
Content blocker prevented frame displaying https://docs.aws.amazon.com/AmazonS3/latest/API/API_CompleteMultipartUpload.html from loading a resource from https://a0.awsstatic.com/s_code/js/3.0/awshome_s_code.js
This completely breaks the navigation system within all AWS documentation — the browser back button does not work and links within the page do not work.
