Spawn egg spawns mobs inside of bamboo

Description

When bamboo is right clicked with a spawn egg, the mob will spawn inside a bamboo nearby, its model glitching inside of the bamboo. It doesn't fall down and just stays there. When raining, zombies and skeletons that spawn this way, they will burn and stop burning sporadically while inside the bamboo. When punched out of it, they stop burning.

Note: they burn sporadically when touching/near bamboo as well, not just when inside it.

 

How to reproduce

Go into a world and plant bamboo in a 3 by 3 square. Make sure they are at least 3 blocks high each, then pick a spawn egg and right click the middle stalk. The mob should spawn inside one of the surrounding bamboo stalks.
