"filter" IE property breaks csso v1.3.0

[doochik]

.ie-test
{
    filter: progid:DXImageTransform.Microsoft.gradient (startColorstr=#33CCCCCC, endColorstr=#33CCCCCC);
}

this code breaks csso

node_modules/csso/lib/gonzales.cssp.node.js:394
        throw message;
              ^
Error in line #3

Also, exception indicates invalid line:

.ie-test
{
    filter: progid:DXImageTransform.Microsoft.gradient (startColorstr=#33CCCCCC, endColorstr=#33CCCCCC);
}


.valid1
{
    left: 0
}

.valid2
{
    color: red;
}

node_modules/csso/lib/gonzales.cssp.node.js:394
        throw message;
              ^
Error in line #13

2w8r: fast local fix — remove space after progid:, everything will be ok. :)
I'll check the validity of this space in MS manuals, thank you.
