I've discovered that changing the doctype does

slight rendering differences. I don't think this will be a big delay,
but I've disabled HTML 5 doctypes by default (in r53137) until I can
figure out the issue and resolve it.
Issue fixed in r53141, and $wgHtml5 re-enabled by default in r53142.
However, it turns out browsers don't treat the doctypes *exactly* the
same, only *almost* exactly (as that issue demonstrated). The HTML 5
doctype triggers slightly more standards-compliant behavior for recent
major browsers in some details of CSS -- which is ultimately good, but
we need to be on the lookout for anything it breaks. This page has
more info on doctype switches in browsers:
