1. Open e.g. replacebycode.html sample and switch to source mode
2. Paste below code
3. Switch to wysiwyg
4. Click behind textarea

<table border="1" cellpadding="0" cellspacing="0" style="width:500px">
 <tbody>
  <tr>
      <td><textarea></textarea></td>
  </tr>
 </tbody>
</table>

Expected result

Cursor is blinking behind the textarea.

Actual result

Browser tab hangs (it is especially painful in Windows because you can't even close the tab).

Other details (browser, OS, CKEditor version, installed plugins)

Problem can be reproduced only in Chrome (Windows and Mac) at least from CKEditor 4.0.

NOTE: It is possible to create table with textarea in wysiwyg mode and then clicking behind the textarea. It will work in that case but as soon as you switch to source, next wysiwyg and then to click behind the textarea, browser will hung.

It seems this issue is not related to textarea only but other form elements as well. I'm closing this one as a duplicate of #17003.
