jsmin and conditional comments

We use the HTML5shiv to enable HTML5 elements in IE < 9. When running a test on a page using this PageSpeed will tell you that 100% of the script can be eliminated, presumably jsmin isn’t recognizing that this is within a conditional comment and thus thinks the script can be compressed.

Would it be possible to get WebPageTests’ PageSpeed updated to run a version of JSMin that doesn’t have this issue?

Your best bet would be to file a bug report on the Page Speed issue tracker: http://code.google.com/p/page-speed/issues/list

Once they update the SDK then I’ll be able to pick it up.
