I think the missing wiki syntax escape that was missing from this issue was fixed by this commit: https://github.com/xwiki/xwiki-platform/commit/c377545b347beebf71cf96656e6ff35de1d80bbf , i.e. XWIKI-13745 and /or XWIKI-13743.

Thomas Mortagne can you confirm that it is so and close this ticket (as fixed by, or duplicate, whatever the rule is) ?

Because for me this is functional today.
