Items deleted when put in a chest at the same time a hopper send the same itemm
I have an automated furnace system and since I had mined a lot of ancient debris, I wanted to melt it down. I started by stopping the hoppers with levers to repair my pickaxe with a some of the debris. I desactivated the levers and wanted to put the scraps i just got in my collection chest. I suppose I put them in at the same time a scrap went into the chest. I think I moved the items over the ones already in the chest and not shift click directly. At that moment the number of scraps glitched, I don't really remember how but something like an instant increase and decrease, it was quick so I didn't really see. I first thought it was a visual bug, but it wasn't. I let the rest melt and could see that 47scraps had disappeared.
Attachedare a picture of the debris before melting (1)(i wanted to flex) and a picture after thebug (2). Also attached are pictures of my system (3,4).Th
isbugis not major but can greatly affect progress if important items are deleted. I think I lost like 1h of my time because of it.Minecraft Bedrock (Win11)
The Bug
When a hopper sends a kind of items in a chest and the player adds the same kind of items at the exact same time as the hopper, the items added by the player are deleted.
Note
The bug was experienced on a realm in survival but works in solo and every game modes.
The bug is a bit hard to reproduce you have to get the timing or brute force it. (Took me 5mins when I recorded it, by brute forcing it)
How to Reproduce{}
1. In creative mode, take a hopper and 2 chests. One chest input one kind of items in the second one.
2. Lock the hopper to provide items to being transferred for the moment.
3. Choose an item and fill entirely the top chest (you could try several times and compare the number of items before and after the manipulation).
4. Take the same item in your hands, do little packs of it to have multiple attempts. (the number of items your adding to the one the slot being filled in the chest is superior to 64 the bug seems to not occurs as the stack and the extra items just switches places).
5. It's a matter of timing (or luck), try to reproduce the rhythm of the hopper in your head or out loud. When you think you have it add the items in hand over the ones in chest. Try again until you succeed.
6. Finally, lock the hopper again and take all the items to the top chest to confirm the loss (if you haven’t seen the bug occurred.

Expected result
Initial:
- X: items in the chest
- Y: items in your hand
Final:
X+Y+1 in the chest
(+1 is the item send by the hopper)
Observed result
Final:
Y+1 in the chest
X disappeared
As I experienced in solo after your answer. I managed to reproduce the bug several times. And so I tested with 8 items in hand and got 9. Which led me to believe that it was the items in the chest that were disappearing (X). But when experienced the first time by accident I lost 47 scraps so may I lost X+Y? I don’t know. Moreover, to complete my report I decided to add a video and as I tried to reproduce the bug I’ve done it with X+Y > 64, that I thought impossible before. And it resulted to be another result:
40 + 32 + 1 => 24 + 8 (in hand)
And: 24 + 8 = 32
Here the result is: Y
When items are added to another items if the amount is greater than 64, You’ll get the rest in your hand. Here 40 + 32 is 64 + 8. So X disappeared as expected and the items even divided correctly. I think the item send by the hopper disappear too in that case because it’s than greater than 64. Maybe that's what happened when I was playing and experienced the bug.

Excuse me for updating so late
This bug still works in 1.19.6 but no other portal will be generated only the player is teleported at the same coordinates he was in the overworld
