Describe the bug
If you shift-click the Portable Cell while having it open, it will be put into the inventory of itself and gets automatically closed, thus causing it to be away.

To Reproduce

1. Open Portable Cell
2. Shift-Click on it while having it open
3. See Issue

Expected behavior
It should not allow to move anywhere while having it open.

Environment
SP

• Minecraft Version: 1.12.2
• AE2 Version: 0.55.14
• Forge Version: 14.23.5.2860

Cannot reproduce on v0.55.29. Please let me know if this is still a problem, and I'll reopen the issue.

Can't reproduce it anymore either on new versions, looks like it being fixed.

For reference: I was able to reproduce the issue again in v0.55.14.
