setRowspan background color

I’m using the sky theme in my grid.

After using the grid.setRowspan(…) command:

If the first row of the “group” is blue; then the spanned cells are blue as well.

If the first row is white; then the spanned cells keep their alternating color.

Using rowspan in XML works fine.

Unfortunately the problem is not clear.
The default behavior is that all the rowspanned cells have the same style as the upper cell.
Such behavior stays in case of loading from the xml or by using the setRowSpan() dynamically.

Image a simple grid with 20 rows using the skyblue theme. The first row is white and the rows alternate blue.

If you rowspan the rows, after loading is complete, in groups of five, then the top 5 rows still show the alternate row colors, the next 5 rows are blue, the next 5 rows are white, and the last five rows are blue.

If I include the rowspan in the XML then the top 5 are white, next blue etc.

If you tell me how to apply the skyblue theme in the snippet editor I will create a quick sample.

Thanks!

Could you please, provide a complete demo, where the problem can be reconstructed locally.
