Setting a minimum width on a region can result in an inaccurate column state after resizing columns. For example on the "Tree with locked Columns" demo setting a minimum width of the "locked" region to 800px and reducing column sizes in this region results in an inaccurate grid state . Outputting the grid state to console shows that the columns widths do not add up to 800px with the final column in the region having a width less than what is visible in the grid.
Would it be possible to have this resolved, thank-you.
