Redstone dust connected to dust down and to the side does not activate blocks in that direction when it is powered from below

Steps to reproduce

  1. Build the layout shown below.
    |hopper|redstone dust|
    |redstone dust|solid block B|
    |solid block A| |

  2. Power the dust on top of solid block B, for example with a redstone torch to the right of it or with a lever on solid block B.

  3. Drop an item on the hopper.

  4. Power solid block A, for example with a redstone torch below it or a lever on it.

  5. Break the power source placed/activated in step 2.

Expected result

The item stays on top of the hopper because the redstone dust on top of solid block B remains powered and pointed into the hopper.

Observed result

The hopper collects the item. It is no longer locked by the powered redstone dust that points into it.

This bug is not not limited to hoppers, as it can also be reproduced with trapdoors.

The solid blocks A and B need not be solid: any block which can have redstone on top works.

Also, I believe the cause of the issue is that the redstone components with this bug are transparent, allowing the redstone to power up the staircase; and take direct powering without forcing redstone dust to route into them. As the redstone dust may not be considered by the game to route into said components in this situation (perhaps due to the arrangement of redstone dust), this bug is caused.

Can also be reproduced with fence gates.
