YUI Problem with hsl() css

[javidabedian]

Hi there ,

when YUI minifying the CSS file , hsl() value saved incorrectly .

I use hsl like this : hsl(0, 0%, 20%);
and YUI save code like this : hsl(0,0,20%);
the second zero must have % to hsl work correctly , but YUI delete the % for zero value is hsl property .

I'm using yuicompressor on phpstorm .

hsla is also affected.
Removed % results into invalid style in browser.
