Some block types aren't symmetrically removed

The following building blocks are not symmetrically removed when one is removed. I tested this on a 4x4 with Normal 4-sided symmetry and a few on a triangle footprint and the results were the same so I didn't test all on a triangle footprint.

• Floor Frame
• Wall Frame
• U Shaped Stairs
• L Shaped Stairs
• Ramp
• Roof
• Roof Triangle

If you remove a triangle floor frame the others are removed, however, it behaves in the same way triangle floor frames do (which will likely be fixed in the next version by the other ticket but is worth mentioning as a test case)
