Issue Summary

When anonymously accessed, the "Related Labels" section shows labels that are tagged on pages in non-anonymous spaces.

This is reproducible on the Data Center: yes

Pre-condition:

1. Page accessible anonymously has been labelled - e.g. label1 and label2.
2. Page that is not accessible anonymously has a label - e.g.label2
Note that both have a common label -label2

Steps to Reproduce

1. Confirm anonymous access is enabled at the global permission level and a bunch of spaces have anonymous access
2. Turn on safe mode in the instance and make sure all add-ons are disabled
3. Log out of the instance
4. Access <baseURL>/label/<label> in the Browser. e.g. <baseURL>/label/label2
5. Confirm can see the "Related labels" items on the right side in the browser and each time I select one, more options pop up to select or change to different ones.

Expected Results

The "Related labels" should not show labels specific to the anonymous pages - e.g., label2.

Actual Results

The "Related labels" show labels specific to the anonymous pages - e.g.label1.

Workaround

Currently, there is no known workaround for this behaviour. A workaround will be added here when available.
