Columns don't autosize width properly when using an indicatorIcon

[A-Posthuman]

When using an indicatorIcon, and the header text is wider than the other cell content in the rows, the header title is slightly cut off due to not being wide enough to take into account the indicatorIcon width.

Can you post a screenshot of this behavior?

First image is from manually setting the grid width to 100% and manually specifying column widths. Second image is with no width set on grid or on these columns, and the autosized result is some of the text is missing.
