Matrix Conditional Formatting Does Not Apply to Row Subtotals and Totals

I have a matrix that I added a measure that creates a UniCode character as an indicator shape and another measure that determines the indicator index values (0-5) under the current filter context. I an using the color by rule conditional formatting using another column (as recently available in PBI) to color the indicator shape. It works on the lowest level displayed rows but not on the summarized subtotal or grand total rows.

As you can see below, drilled dwon one level, the formatting applies to Services, but not Income.

Then drilling down another level, Ohthe, Basic Exam, etc has the formatting, but the subtotals of Income and now Services do not. The correct value at the subtotal level to perform the conditional foirmatting is correct, but it jusdt not applied. 

Is there a setting for applying on subtotals and totals or is this a possibly a bug, not yet implented extension of the functionality?  Please tell me not by design :-)

Thanks
