Combined query string that produces unexpected results

?a.balancewhite=true&s.brightness=0.36

Individual query strings that produces expected results

?a.balancewhite=true
?s.brightness=0.36

Do you have images of actual vs. expected? I'm seeing what I would expect - the white balancing happens first, followed by a brightness increase of 36.
