Gjs-css-rules invalid sort

Hi,

On the latest version 0.15.10, we have a problem with the css generator. Devices is configured like this :

mediaCondition: 'max-width',
deviceManager: {
	devices: [
		{
			name: 'small',
			width: '40em',
		},
		{
			name: 'medium',
			width: '64em',
		},
		{
			name: 'large',
		}
	]
},

When I add a rule like background-color, on the real css I have

<style>
@media (max-width: 40em)
.id-usr-ix0a {
    background-color: #ff0000;
}

@media (max-width: 64em)
.id-usr-ix0a {
    background-color: #828282;
}

.id-usr-ix0a {
    background-color: #000000;
}
</style>

This order is perfect. But on the javascript style (for editor) I have

<div id="gjs-css-rules"></div>
<div id="gjs-css-rules-40"></div>
<div id="gjs-css-rules-64"></div>

So my CSS result on editor is

<style>
@media (max-width: 64em)
.id-usr-ix0a {
    background-color: #828282;
}

@media (max-width: 40em)
.id-usr-ix0a {
    background-color: #ff0000;
}

.id-usr-ix0a {
    background-color: #000000;
}
</style>

And the style under 40em is the 64em ....

Have you an idea of the correction ?

Thanks a lot !

Flo.
