[css-grid] grid shorthand property doesn't specify gutter properties

According to the spec, grid-column-gap and grid-row-gap can be set by the
grid shorthand property:

> The grid property is a shorthand that sets all of the explicit grid
properties (grid-template-rows,grid-template-columns, and
grid-template-areas), all the implicit grid properties (grid-auto-rows,
grid-auto-columns, and grid-auto-flow), and the gutter properties
(grid-column-gap and grid-row-gap) in a single declaration.


However, the gutter properties don't appear in the Value line:

> Value: <‘grid-template’> | [ <‘grid-auto-flow’> [ <‘grid-auto-rows’> [ /
<‘grid-auto-columns’> ]? ]? ]


I'm specifically wondering whether something like:

grid: 4px


is equivalent to:

grid-column-gap: 4px
grid-row-gap: 4px
