      Description

      Certain block entities, when newly placed next to a power source, won't activate until they receive a block update.

      Steps To Reproduce:
      1. Place a command block to where it will be powered as soon as it is placed.
      2. Type a command into the command block, e.g.: "say test".
      > Notice the command block won't output "test" although it's powered.
      3. Cause a block update next to the command block.
      > Notice the command block now outputs "test".

      This also occurs with dispensers, droppers, and note blocks.

      See also:
      MC-51340, it also happens if you got certain block entities with NBT data (e.g. a command block with an inserted command) and place that manually next to a power source, as well as
      MC-31100 if you setblock certain block entities with NBT data where they would get powered, as well as
      MC-80901 as falling block.
