Another clawfoot faucet question

So a big thanks to everyone who helped me with the faucet connections (compression vs mip). Every thing is hooked up and no leaks.

Here's my question, I hooked all the supply lines up ran hot for a few cold for a few both for a few, all while occasionally turning on the diverter, I'm satisfied and go sit down to watch tv and 15 minutes or so later a random trickle of water comes out of the faucet spigot.

Is this normal?
