Bug: Double-clicking the first column header border in a grouped table view does not resize it correctly

[chenilim]

Steps to reproduce the behavior

1. Open a grouped table view
2. Double click on the right margin of the first-column's heading
3. The column resizes only taking into account the top-level grouping

Expected behavior

The column should resize so that all cells in the first column are visible.
