This is where our job becomes tricky. Do we, number one, cite building codes, number two, do we split hairs (it is afterall barely 1'' short) and if we do write it up what kind of rating do we give it: defective, monitor, minor defect, dangerous because it is technically not deep enough? Use your best judgement. It is highly unlikely it would ever be an issue but to be on the safe side, it should have been in the report. It's the things you don't put in your report that may come back to haunt you.
