This is a common problem (feature?) with hot water faucets.
A faucet is very much subject to thermal expansion, being
mostly metal.  When you first turn on the water, the pipes
have cold water in them.  When the hot water reaches the
faucet, its dimensions change sufficiently to alter the
washer clearance at the valve seat.  Monitor the change
in flow while feeling metal parts of the faucet sometime...
