Outlook keeps only the first class in `class` attribute, ignoring everything else

[e1himself]

UPD: This is a duplicate of #75

Stylesheet:

<!--[if gte mso 9]>
<style type="text/css">
.red {
    color: red;
}
.large {
    font-size: 72px;
}
</style>
<![endif]-->

Markup:

<div class="red">
    THIS SHOULD BE RED IN OUTLOOK
</div>
<div class="large">
    THIS SHOULD BE LARGE IN OUTLOOK
</div>
<div class="red large">
    THIS SHOULD BE RED AND LARGE IN OUTLOOK
</div>
<div class="large red">
    THIS SHOULD BE RED AND LARGE IN OUTLOOK
</div>

Result:

As far as I see, all versions of Outlook are affected. Including the newer ones.

I think this is is the same as #75

Ah, you're right. I have searched if this was already reported, but somehow missed it.

Thanks!
