    <thetext>In certain conditions, the grid item logical height computation in the grid track sizing algorithm will modify the overriding containing block size for the grid items&apos;s block direction and mark the grid item dirty for layout. This dirtying occurs even if the override size remains the same. This can result in bad performance in certain pieces of content (e.g. nested grids)</thetext>
