This is doing even stranger things if the style tag appear within a nested table. The content gets duplicated, and on the fullpage demo, the source can not be edited again, and submitting does not work.

Also some of our users have experienced this causing their browser to crash. It appears that there may be a long/infinite loop that is crashing the browser.

Though neither valid HTML nor XHTML allow <style> inside blocks, while it's a habit of web developers that we could show some tolerance here.

That fix seems to work in my case, but there is one more associated issue. It used to be common practice to put HTML comments inside style tags to prevent the style from causing issues in browsers that did not support css. Many of our users still do this. For example:

<style type="text/css">
<!--
p{color:red}
-->
</style>

Becomes in the final output

<style type="text/css">
<!--{cke_protected}{C}%3C!%2D%2D%0Ap%7Bcolor%3Ared%7D%0A%2D%2D%3E-->
</style>

The HTML comment in the stlye tag gets protected, but not un-protected.

Replying to skisulli:

That fix seems to work in my case, but there is one more associated issue.

Obviously that's a different problem, and it already has its own ticket: #4880
