Auto grid rows and columns not working

[geom3trik]

Auto grid rows and columns should use row_max and col_max to determine their width/height. Calculating row_max and col_max requires determining which children will be in which row/column before calculating the sizes of the rows/columns.

row_max - max height of children in row
col_max - max width of children in column

Normally, child width/height is ignored when using grid layout. Does it even make sense to have Auto rows/columns?
