Expected:
After creating a compound with Compound Creator, user would be able to add it to inventory.

Actual:
Tapping the new compound crashes the app.

Repro:
Use a world with Education Edition enabled, build a simple compound with Compound Creator, e.g. a stack of two H in one slot and one O in another slot.  This results in an H2O compound in the output slot.  Tap the H2O and the app crashes.  Reproduces every time.

Found a similar issue in MCPE-36949 prior to entering this, but there wasn't enough detail to confirm it was the same bug.
