RequestReduce messes up the calc() CSS function

[russiarulez]

In my CSS I'm using the calc() function - for example "height: calc(100% - 30px);".
I noticed that some parts of our website are messed up, and after turning off RequestReduce the layout becomes normal.
After a brief investigation I found that everywhere the calc() function is used, a space after the '%' is removed, so the above example becomes "height: calc(100%- 30px);" (note that there's no space following the '%' sign), and this breaks the function, as you must have the spaces surrounding the operator.

I am seeing this too.

This looks like a bug in an old build of the AjaxMin library. Get the latest RR code and update the AjaxMin nuget package and it will work.

I still have this problem here in 2019. I don't have AjaxMin in my project, and installing it didn't help. I've also tried reinstalling RR, but that didn't help either. Does anybody have any suggestions to how I might fix this?
