This is a bug I found in both Minecraft 1.8.9 and 15w51a (originally, still happens in 16w02a), in which hoppers don't respond to redstone changes. In the imgur album, Pictures 1+2 are using a similar setup: power torch, manually update the hopper, remove power source, take screenshot using Print Screen, save it in Paint (since that's what I have on hand), move on to the next picture. For Picture 3, I just directly powered the hopper and it didn't work.

Jordan Finch is right, this is redstone state changes failing to update hoppers and make items flow or stop flowing

I cannot reproduce the issue you are describing. The imgur gallery looks exactly like the linked duplicate ticket. Please provide detailed steps to reproduce the issue you claim is different from MC-60242.
How is this a duplicate of MC-60242? That bug only affects block models. This bug affects hopper behavior, not hopper models.
UPDATE: It looks like hopper behavior has been fixed. Now the only issue is that the F3 screen is showing the "enabled" tag on hoppers wrong, which is what lead me to think that hoppers were still broken.
