On Confluence 6.15.4
Based on the 404 reports from our pages it looks like the assitive skip link to #title-heading is broken.
The folllowing set of links are defined for each page, and the first #title-heading is malformed due to the leading "\" on some pages. This is impacting SEO.
There seems to be no way to disable this feature or a manual override that fixes it.
