[MC-193457] Dropper/Dispenser 'Triggered' block state not updating without player interaction

When powering a Dispenser or Dropper, the "triggered" tag remains stuck until the player opens its inventory

for example:
false -> powered -> remains false -> player opens inventory -> becomes true

true -> unpowered -> remains true -> player opens inventory -> becomes false

notes:
-video showcases a resource pack tweak I was working on that changes the texture if 'triggered = true'
(I have only added this for the dropper, thus why the dispenser does not change)
-causing a block update does not trigger a block state update, only the player opening its inventory

edit: hopefully the gif works, video wasn't loading for me

Hi there!

I had this issue happen to me a few days back when I was working on a bartering farm. I can confirm this. Also can confirm for 20w27a.

Is this not just quasi connectivity?

can confirm that this is still present and that it is not just being powered strangely via qc as eatmyvenom asked. It may have to do with weird code from qc and it not updating the client, but these droppers and dispensers are being powered directly. it is simply a client server desync of some sort, my guess would be that the server is not sending updates to the client when the block state changes.

Duplicate of MC-70127.

Can confirm in vanilla 1.17 Also, may be duplicate of MC-203079.

Also, I don't think this is a duplicate of MC-70127. That bug is related to the debug screen not properly displaying the server-side block state, whereas this bug is a block state not properly being updated.

Can confirm in 1.19.4. This also affects some block states of hoppers, sugar cane and cactus - should these be reported separately?
