Multiblock with Sterilization Hatch not working in Cleanroom

[ChromaPIE]

• In a formed and working cleanroom, build a multiblock that runs recipes requiring an sterilized environment, in my case, it's the megaLCR
• Have an Auto-sterilization maintenance hatch in its structure
• It can't run the recipe

If you break the cleanroom's structure, like breaking its core block, then break and place the megaLCR's core block again, it'll start running the recipe. While the recipe's running, place the cleanroom, the recipe will stop right away.

Expected behavior will be the structure being able to function as intended ignoring external environment completely.

Due to how the cleanroom code works, a multiblock will have its cleanroom set to the type of the cleaning hatch only when it forms. But if it's inside a cleanroom multiblock, the cleanroom will override what the hatch set.
Where the sterile hatch sets the cleanroom type:

ZBGT/src/main/java/com/zorbatron/zbgt/common/metatileentities/multi/multiblockpart/MTESterileCleaningHatch.java

Line 55 in 94215e5

cleanroomReceiver.setCleanroom(DUMMY_CLEANROOM);

Where the normal cleaning hatch sets the type: https://github.com/GregTechCEu/GregTech/blob/9fe140febe8747bbe2f06dfd570421331ec06f4b/src/main/java/gregtech/common/metatileentities/multi/multiblockpart/MetaTileEntityCleaningMaintenanceHatch.java#L57
Where the cleanroom sets the receiver's cleanroom type (which gets run every structure check): https://github.com/GregTechCEu/GregTech/blob/9fe140febe8747bbe2f06dfd570421331ec06f4b/src/main/java/gregtech/common/metatileentities/multi/electric/MetaTileEntityCleanroom.java#L461
I'll look into fixing this in GT, but since a new release of GT isn't likely to come out in the foreseeable future, just don't build your sterile hatch multis in a cleanroom multiblock for now.
