Summary:

Sand/gravel turns into an item when it breaks itself even with tiledrops off

Impact:

Gamerules not doing what they're supposed to is a problem, especially when coupled with bug MCM-860, the player could get erroneous items in their inventory causing for a bad player experience in adventures.

Repro Steps:

• Open the repro world (attached).
• Walk down the corridor pressing the buttons randomly
• note that on the first button press, the gamerule gets updated to gamerule dotiledrops false
• eventually a sand/gravel will break itself

Observed Results:

When the sand/gravel breaks under its own weight, it drops an item.

 

Expected Results:

When tiledrops are off, no tiles should drop ever, whether you break them yourself or if they break themselves.

Regression Builds:

Was tested working in:
probably never worked.

Notes:

Because of MCM-860 which results in erroneous block drops, this is a much larger issue than it should be.
