we are heavily using the panel-macro in our 2.5.* instance and are using of course parameters.

When i upgraded a testinstance to 2.7 it seems that css2 has a big problem with case-sensitive values. I have two points which are not very smooth:

1. keys which the macro dont knows are just ignored
2. values which are correct but case sensitive wrong are printed as failure (as you can see on the attached screenshot

a "fix" would be good as i cant scan my whole instance for macros which have this problem, or can i?

I also wrote a support request at https://support.atlassian.com/browse/CSP-14100 but there it was stated as not supported customization (am i doing something wrong here), at least i didnt get to it.
