I hope the sealant spins with the rest of the tire. It is a vicous fluid. If it doesn't, then you have fluid resistance (like air resistance, just a whole lot more) between your stationary fluid and rotating rim/. (Reality check here - it won't take long at all for that resistance to have speed up the fluid to tire speed, so it will rotate.)
