Items can go through walls if in a skinny room with deep water.

Here is the recording file zipped up into a .zip file

Fast forward the recording to turn 1150 on Depth 3. Then, turn on omniscient view. Then, slowly step through what happens.

1. I enter into deep water, which immediately causes me to lose items (expected).
2. I use the search feature in deep water, which causes me to continue to lose items, since I am in deep water.
3. Items slip through the wall, causing them to surprisingly disappear from view.

In my opinion, this is a bug. But even if it is not, I see nothing similar in the Issues tab, so this is worth submitting regardless.

Finally, here are some screenshots for those who cannot play the recording.
