I just started a game, cast a rain spell (prior to initiating combat, though I'm not sure if that matters) to make some puddles.
In the battle, I electrified the water, and my cleric and the monsters were both standing in it. The water remained and we were repeatedly stunned in an infinite loop with no disappearance of the water (>15 full rounds of combat).
If I clicked a lot I could eventually break through the loop and take a tiny move action to escape the puddle.
This happened repeatedly when I tested it two more times.
