The context element only makes sense in the fragment case and not defined otherwise. It is possible to run into this problem when parsing "<head></head><template></template>".

I try to be quicker with parser bugs but this one went under my radar for some reason. 96475 3 contributor 2013-11-18 23:34:49 +0000 Checked in as WHATWG revision r8293. Check-in comment: The 'reset the insertion mode' algorithm referenced the context element in some cases where there was no context element (e.g. '<html><head></head><template></template>') http://html5.org/tools/web-apps-tracker?from=8292&to=8293
