  alert("Hello World!");
</script>

It's kind of reveal limitation. As the content will be parsed by browser.

You can use zero wide space \u200b to break these kind of characters.

I try to add a patch and it works. And I think this should be built at your side.

Alright, I think this is a solution good enough as this is a upstream issue. Thanks a lot for that!
