Portable hole focus goes through cleanroom

[Oculatus]

Describe the bug
Most multi's, when using the portable hole focus either on it, or a block before it, will no be affected by the portable hole. The cleanroom on the other hand is affected by it. When you use a portable hole focus on the cleanroom, it will make the structure incomplete, and cause it to no longer be clean.

What Version (if GTNH)
GTNH 2.5.1

To Reproduce
Use portable hole focus on cleanroom wall.

Expected behavior
It should either not work on the cleanroom like other multis, or, the "portable hole" blocks, could be added as a valid block for cleanroom structure, so that it does not deform, and then does not stop processing.
