1) open an html file
2) put following code somewhere inside:

    <script language="javascript" type="text/javascript">
        function functionAlpha() {
        }
    </script>

=> the javascript has no green background
3) close/reopen the file
=> the background is ok

The update of the HL doesn't work after opening - if you for example change the <script to <sXcript the green background
should disappear.

This looks like to be a recent regression of the HL performance improvements. Please consider fix of this to go to 61
patch 1 as well.
