The Ender Pearl make entering and blocking the player in some blocks

Sorry for my english, I'm Italian.
When I launch two Ender Pearl on a block of ice or glass, I get stuck in them.

What I expected to happen was...:
When I launch two Ender Pearl I would have fallen to the ground normally.

What actually happened was...:
When I launch two Ender Pearl makes me go inside the ice/glass and I can cross it.

Steps to Reproduce:
1. Launch the first Ender Pearl on the block of ice/glass so that the player remains suspended in the air
2. Launch the second Ender Pearl in the same point so that the player enter in the block and can move freely in it
