Describe the bug

To Reproduce
1. Put items inside a portable cell.
2. Open and drop the cell at the same time.
3. Take the items from the open cell, and take the cell from the ground.
4. It's all, see the video for more info.

Expected behavior
The GUI to close immediately after the portable cell is dropped

Environment

• Minecraft Version: 1.12.2
• AE2 Version: rv6-stable-6
• Forge Version: 14.23.5.2836

Cannot reproduce. We also check constantly, if there still is a portable cell hold and close it when needed. So please reproduce it with AE2 alone to rule out any other mod breaking it.

Forge: 14.23.5.2838
AE2: rv6-stable-6
Only Forge & AE2 installed.

I still can reproduce the bug.
It's really hard to reproduce without some lag, so I changed my render-distance to 32, to try generate some chunks and get lagged.

It worked for me on a server to which I had quite a bit of lag. For me, I needed to right click a slight bit before hitting Q.

Working with 50ms, you must be very fast

Is there any time frame on when this will be included in a new build on curseforge or the website? I've checked but there is not one yet and this is a fairly big issue/problem.
