v5.1.0 CSS Grid: question about `.g-start-0`

Created by: cccabinet

Looking at the recompiled CSS with the CSS grid enabled, .grid .g-start-0 { grid-column-start: 0; } is included.

grid-column-start: 0 is an invalid property value. So, .g-start-0 is not needed. I think you'll need .g-start-12 instead.
