[MC-136736] Sea lanterns drip when water is above them

The bug

When sea lanterns are placed with water above them and air below, they generate dripping water particles like solid blocks. This is different from how they behaved in 1.12.2, when they would act like glass and be watertight.

How to reproduce

Construct a 5×5×2 bowl out of glass, with a sea lantern in the middle. Place water in the bowl. The sea lantern will show dripping water particles in 1.13.1 but not 1.12.2.

Can also confirm. In 1.12.2, sea lanterns did not drip water particles but in 1.13.1 they do because they did not receive the block tag impermeable.

Confirmed for 1.13.2-pre1.

Surely this would be an intentional change since sea lanterns are impossible to see through? Simply because the behaviour is different doesn't mean it's a bug.
