[css3-grid-layout] Suggestions for terminology amendments (additional!)

Just spotted another terminology mismatch.

http://dev.w3.org/csswg/css3-grid-layout/#grid-declaration0

Here: 'The baseline of an inline Grid element is the bottom edge of the margin box.'

This is confusing. A Baseline – in design terms – is a typographic measurement (the bottom of a character). In grid design there is such a thing as a 'baseline grid' – a grid comprised of a vertical division of space according to the type size from baseline to baseline. Unless I'm confused, I don't think is what this definition is referring to.
