--- Comment #2 from zalan <zalan at apple.com> ---
This is about integral based alignment vs. non-integral based box model values
e.g:
vertical-align: -0.5px; -> turns into 0px
margin-bottom: 0.5px; -> stays at 0.5px

these tests trigger this mismatch through the combination of 'font-size: 15px' and 'align/margin -> 0.5em'.

Legacy line layout is historically integral based, while IFC is not, currently it is forced to match legacy behavior through explicit flooring/ceiling of certain values.
