This doesn’t exactly answer the question as asked, but some comments allegedly from the EU Commission are pertinent:
“A spokesperson of the European Commission … pointed out that persons who at the expiry of their visa have already stayed 90 days in any 180-day period should be issued a national long-stay visa or a residence permit covering the prolonged stay, in the country in which they have been stranded.
“More generally, as regards, third-country nationals who are stranded in the EU and as a result overstay their short-stay or long-stay visa or their residence permit, or who stay beyond the authorized visa-free maximum period of stay, a border guard can always make an exception if properly documented,” the spokesperson said.
