Hi devs,
Due to special circumstances (hitting XWIKI-5166 while upgrade
XWiki.org to 2.3),
we've face the<body> database className conflict again, on
code.xwiki.org.
What happens is that the "code" DOM class name is apposed to the body element
(see htmlheader.vm), and this interferes with styles defined for the {{code}} macro.
Potentially there are other scenarios where class names can conflict with database names.
I propose we prefix the apposed class name with "wiki-" (that's what
we've been doing on
xwiki.org for some time now) in order to avoid this.
Though, we need to agree on this, since it can be a
breaking change for those who relied on that "feature" to skin differently
different wikis on a farm.
