Object layout ignored when entryLayout = `content`

[ExpensiveKoala]

Currently, achieving something like this is impossible:

(The address object field at the bottom right)

This is because when entryLayout is set to content, the span values are set to ${FIELD_GRID_COLUMNS} due to the container's width.

Lines 40 to 42 in 63c767b

	[belowTablet]: {
	gridColumn: `span ${FIELD_GRID_COLUMNS}`,
	},

When layout is specified, it should prioritize that value vs attempting to be responsive.
