Screenshot of the example

The HTML (with JavaScript) highlighter matches "/>" even in JS String literals.
Also in RegExp, when the regexp starts with ">", forming a "/>".

Steps to reproduce:

1. Change highlight mode to HTML
View > Highlight mode > Markup > HTML
2. Type <script> tags, inside them, type a String literal with "/>" inside.
Example: <script>"abc/>def"</script>

JS highlighting stops after the />, and becomes HTML highlighting, even when in <script> tags.

Example .html file:

<script>
var a = "abc"; &amp;
var b = "abc/>abc"; // JS highlighter stops here
var c = "abc"; &amp; // &amp is highlighted, HTML highlighter here
</script>

<script>
var a = /regex/; &amp;
var b = />regex/; // JS highlighting stops every time there is this string "/>"
var c = /regex/; &amp;
</script>

<div id="xyz/>xyz" />
<!-- No problems here in HTML -->
<div />
