Minecraft – Whoa! How did the water not go flowing everywhere

minecraft-java-edition

I was building an elevator with water and all that, when I accidentally broke open the door, but water didn't flow everywhere! But when I broke open the door on the first floor, water came gushing out! Is this a glitch or something?

This is because the water on the first floor doesn't have anywhere to flow but out where the door used to be. This is because the block at the bottom of the elevator doesn't go down one. I would suggest setting something up like this to prevent that.

| {}[]
| {}[]
[]{}[]
[][][]

|
| = Door
[] = Block
{} = Water
