Nested ifs in html don't operate as expected

[boostermedia]

For example:

    <!-- #if __chrome
        <script id="booster-api" type="text/javascript" src="../../shared/booster/api.js"></script>
    <!-- #else  -->
        <!-- #if __target='dev' -->
            <script id="booster-api" type="text/javascript" src="shared/booster/api.js"></script>
        <!-- #else
            <script id="booster-api" type="text/javascript" src="/shared/booster/api.js"></script>
        <!-- #endif -->
    <!-- #endif -->

I'll take a quick peek at this in a few hours when I get the chance. From what I can remember if statements were not meant to be nestable, but I'll take a look.
