Rain appears to persist even when the weather supposedly is not raining.

This so far has only occurred once and happened when:

Slept in a bed to pass the night while raining.

Expected Result:

The player passes the night and the weather changes to clear, removing the rain graphic in the world.

Observed Result:

The player passed the night and the weather changed to clear, but the rain graphic remained in the world.

This was observed when it appears to be raining but endermen weren't taking damage and undead mobs were burning (confirming that the weather is clear)

This bug continues to occur even after sleeping through the succeeding nights.

Note that quitting and relogging resolves this bug.
