User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:38.0) Gecko/20100101 Firefox/38.0 Build ID: 20150513174244 Steps to reproduce: Compare the following pages: SVG file: http://upload.wikimedia.org/wikipedia/commons/e/e1/SystemLanguage.svg Same code as inline HTML in a JSFiddle: http://fiddle.jshell.net/q56sj6kg/ If they look the same, play around with your preferred content language settings & reload. Actual results: The language switch in the SVG file respects the "allowReorder" attribute, and selects the user's preferred language if it is available. The language switch in the HTML file always uses the first option that matches *any* of the users' content languages, regardless of whether the "allowReorder" attribute is included. Expected results: Both SVGs should have the same behavior.
This is not currently a valid bug as we're following the html parser specification. The html parser should be changed to support it (i.e. allowReorder being camel cased should not be lowercased in SVG) This is a html parser issue. Changing the parser to support this should be accompanied with a corresponding spec change on https://www.w3.org/Bugs/Public I assume you can raise a html spec bug and report back on its progress Amelia.
OK, to recap the problem: the HTML parser automatically lowercases the attribute, but Firefox's SVG switching code only looks for the canonical mixed-case version. To Do for me: * Get allowReorder in the SVG 2 specs. * Get allowReorder in the mixed-case tag list for the HTML parser. I don't think I'll get much traction on the second point until I take care of the first. In the bigger picture, this will be covered by the plan to make all SVG parsing in HTML case-insensitive. However, the exact details for implementing that are still being debated. I'll follow-up when this is actionable.
looks like SVG 2 will drop allowReorder

Thanks for following up, Robert. Normative text isn't in the spec yet, but the SVG working group issue is here: https://github.com/w3c/svgwg/issues/136 As Robert notes in Bug 1279690, the resolution is to always have the allowReorder behavior and therefore not need the attribute and special HTML parser rules for it.
