Defect in Get Table Cell Element with rowspan and colspan

I am trying to assert values in an HTML Table using “Get Table Cell Element” keyword. The table header th element uses rowspan and colspan. See screenshot.

element has the wrong value in the call below. It is returning the value in column 0 “Thing 2” instead of column 1 “A2”.
${element} = Get Table Cell Element ${table} “Sub Category A” “Thing 2”

This keyword only calculates td and tr.
Rowspan and colspan are not taken into account.

So you can not use this keyword for these table.
