Burning fuel icon not decreasing when the world is closed and reopened

The burning fuel icon in the furnace will not decrease if a world is closed and reopened. Items will still smelt and the fuel source will expire after the normal time period. I have only noticed this when using a lava bucket as fuel.

The burning fuel icon in the furnace GUI will not decrease if a world is closed and reopened. Items will still smelt and the fuel source will expire after the normal time period (which immediately deactivates the furnace, as expected).

0Tested in survival mode, using lava buckets, coal blocks, and coal/chacoal as fuel.
