Timeline chart grid column color not working

[GeorgEduard]

On any chart, if xaxis type is set to 'datetime', grid column customisation is not working. If xaxis type has no setting, or other than 'datetime', there is no issue.

Steps to Reproduce

In the options, set the xaxis type to 'datetime';
In the grid column section, add some colors or other styling - nothing happens;
Remove xaxis type, or set type="category" - styling is now appearing;

Expected Behavior

The columns should change color, or whatever valid setting I add there.

Actual Behavior

Nothing happens if you change something there.

+1; I'm seeing this same issue. Colors are not being set for 'datetime' type.

It seems as though the grid lines are being set correctly for 'datetime' axis when grid.xaxis.lines is set to true;
Though colours are not being set when using grid.column.colors with the 'datetime' axis
