Arron,

I have decided to just approve (review) those 2 tests as they are indeed
testing what they intended to test and that the pass/fail conditions
sentence is appropriate, adequate. But, as coded, the layout is not
accurately predictable; therefore it's not possible to create reliable
reftests for those tests.

line 27 #cell {width: 1in;}
is unneeded though in
border-bottom-width-applies-to-014
