Read/Write of styles gap and grid-gap swap the order of col and row

[Dan Hazel]

Bug Report

Description

A style read as:

grid-gap: 10px 80px;

is written as:

grid-gap: 80px 10px;

Similarly, a style read as:

gap: 10px 80px;

is written as:

gap: 80px 10px;

Possible Solution

row and col are incorrectly assigned here:

and here:
