RE: [css3-grid-layout] mismatched grid template strings

I agree the spec should say so.  The grid-template property is underspecified compared to Bert's template layout module.  I've opened another issue to declare that non-rectangular grid cells are not allowed [1].  Specifically, non-rectangular grid cells or multiple grid cells with the same letter are invalid and cause the declaration to be dropped.

The spec should say so then, and say what happens if an author tries to create that shape. Does the whole template get thrown away, or does it create a new box on the row where a connected box would be invalid?
