Walking through Glass with a Enderpearl

You're able Walking through Glass, by simply throwing a Enderpearl on the ground right in front of the Glass wall (while you are Standing right in front of it aswell).
Since spamming Enderpearls has been removed through a cooldown, and therefor preventing any Wall Glitch Stuff to happen, I consider the possibility throwing through Glass with an Enderpearl as a Glitch/Bug.
