No they don't, not if you install the wheel properly! I've put thousands and thousands of miles on fixed gear and ss drivetrains with horizontals, and for that matter with track ends without chain tensioners, and never had slippage even during 7-mile standing climbs (I'd sit every half mile or so for a few hundred years; this was when I was a young spry 50-something) or when pacing cars to 20 mph at stoplight drag races. *And* this includes wheels secured with steel internal cam QR skewers.
After all, Eddy Merckx and peers used QRs on horizontals and even they didn't report problems with axle slippage, even when sprinting or climbing a col in the 42 X 24. Hell, I've even used old fashioned wingnuts (SA proprietary ones) on horizontals and, well tightened, I experienced no axle slippage. The only time I had axle slip with horizontals was when using an allen key skewer with aluminum end caps; I once tightened one down so much that the skewer snapped, but the aluminum (serrated) caps simply didn't bite into the dropouts enough. But I can tell you from almost 30 years of experience that horizontals don't cause slippage even with QRs, let alone track nuts.
