Issue Summary

When a user uses the “tab” key to navigate the Confluence pages in Confluence version 10.2.17+, there are few items which are in focus, but there is no outline box on them, which makes it very difficult for the user know what is in focus.

Steps to Reproduce

1. Install Confluence version 10.2.17 or 10.2.18
2. Create a Site -> Space -> Page.
3. In the view mode navigate screen using tab key ( keyboard).
4. Observe that some of the items are highlight with a box and some are not.
5. Please ref. to the screenshots below.

The behaviour is reproducible in the latest 10.2.x releases but absent in earlier versions and the 9.2.x LTS branch.
 

 
Key Finding: The regression was introduced between 10.2.15 and 10.2.17. This suggests the cause is likely tied to changes incorporated in the 10.2.17 release

Expected Results

All items are highlighted as in the previous versions.

Actual Results

Please refer to the screenshots below. There are no errors reported in the logs or the browser.

Workaround

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