Fountain shield movement blocking

I get that the shield is supposed to keep everyone inside the spawn area until the shield goes down, but if you click to move outside of spawn and the shield drops during the path movement, the character still stops at the shield wall even though it went down.

Kind of just an annoying little bug since sometimes I'll buy everything, right click to walk to lane and then look away from my screen only to see that my character is still sitting at spawn because they stopped at a wall that was no longer there.
