Extra space in pseudo-elements and pseudo-classes selectors

[foulmetal]

Description

When using rule with a pseudo-elements or pseudo-classes selectors inside a :not() selector and this rule is nested in another rule, less beautify add extra space after the first colon

Input

.one {
    color: #FFF;
    span:not(*::selection) { // pseudo-element
        margin-top: 0;
    }
}

.two {
    color: #000;
    span:not(*:active) { // pseudo-class
        margin-top: 0;
    }
}

Expected Output

The code should have looked like this after beautification:

.one {
    color: #FFF;
    span:not(*::selection) {
        // pseudo-element
        margin-top: 0;
    }
}

.two {
    color: #000;
    span:not(*:active) {
        // pseudo-class
        margin-top: 0;
    }
}

Actual Output

The code actually looked like this after beautification:

.one {
    color: #FFF;
    span:not(*: :selection) {
        // pseudo-element
        margin-top: 0;
    }
}

.two {
    color: #000;
    span:not(*: active) {
        // pseudo-class
