No, extending the voting period for these is the whole purpose of holidays.
The "If some Rule bases" paragraph clearly doesn't apply to these. The "If some Rule requires" paragraph might, though. 2006-07: 4877-92 started after the holiday, 4874-75 ended before. Zefram's proposal history indicates that 4876 also ended well before, and that 4875-76 had botched text. 2005-06: 4847 started after, 4846 ended before. 2004-05: 4628-31 ended before, 4632-33 were potentially affected (but 4632 failed regardless and 4633 was ratified in February for other reasons), 4634-35 started after. 2003-04: 4543-44 ended before, 4545-49 started during (but the results were probably still valid), 4550-51 started after. 2002-03: 4425-26 ended before, 4427-31 started after.
