Time doesn't start until you destroy something

It did happened in version 0.4.0 too so I checked in the recent update. Exploring a NEW WORLD without destroying anything will make it day forever in survival. I do it all the time when putting in random made-up seeds to check plants (especially mushrooms), animals, biome and terrains. Also, and I'm not sure if this is intentional, but when generating a seed in creative no mushrooms are visible. In survival they are.
