Print will gen in air on some special situation

[Rivmun]

They're hard to detect and calculate for now. Will not be fixed in short term.

• Entity jump passively. i.e., get hit by others, thrown by iron golem, get knockback, and more...
• Rabbit moving.
• Standing on block edge and no air below. (in 0.2.3 #18 )

Rabbit can gen print, but that print will instantly dead. Considering its print gen on air due rabbit moving with Y axis.
But if rabbit moving IN grass block, print will correctly gen.
