Space before CSS attribute selector improperly trimmed

[callmevlad]

If you run the following code through http://jsbeautifier.org/:

<style>
    html.js [data-custom="123"] {
        opacity: 1.00;
    }
</style>

The resulting CSS is broken:

<style>
    html.js[data-custom="123"] {
        opacity: 1.00;
    }
</style>

The input code has a selector that means:

Select all elements with attribute `data-custom` *inside* of the `html` element

But the output CSS means something completely different:

Select the `html` element *with* a `data-custom` attribute

The space after html.js should be preserved in the output.

One current workaround for this (if you have control over the input CSS) is to add a * selector before the attribute declaration:

<style>
    html.js *[data-custom="123"] {
        opacity: 1.00;
    }
</style>
