Yes, you are right. The tested assertion is
https://dev.w3.org/webfonts/WOFF2/spec/#conform-mustRejectNonEmptyBBox
which is clearly marked as an AT assertion:

*AT *an encoder MUST check that the glyph bounding box values are all 
zeros and, if this condition is not met, MUST reject an input font as 
invalid.

I have deleted all results for that test. I have also marked the test 
(and the reference for it) as Rejected. I think this removes the test 
from the test suite once it automatically rebuilds which, I believe, 
happens once a day.
