Any occurence of '/>'  terminates a script (or style) tag, so the following code is highlighted incorrectly.

<script>
document.write('abc<br />def');
var a = 1;
</script>

<script>
// document.write('abc<br />def');
var a = 1; 
</script>

<style>
/* here's a  <br />  style */
br { line-height: 2px; }
</style>

<style>
.tag::before { content:"< "; }
.tag::after { content:" />"; }
</style>
