There are many other supported MIME types that are associated with the JavaScript language (e.g., text/ecmascript or application/javascript). With Bug 332488, we've updated the partitioner for these MIME types, but notice an exception whenever content assist is invoked in the script block with them. Just having something like:

<script type="text/javascript">
var m = document.getElementById("a");
</script>

and invoking content assist inside results in:

I suspect our translator needs a similar boost to its list of allowed languages/mime-types to include.
