Google Chrome hangs when CKEditor parses malformed HTML

[Nicolás Cardelino]

Steps to reproduce:

1. From Google Chrome open the CKEditor demo page (​http://ckeditor.com/demo) and go to the Source view.
   
2. Paste the following malformed HTML:

   <span id="sample" overflow="hidden" ;"="" style="font-size:8pt; font-weight:normal; font-style:normal; color:#808080; background:transparent">Text</span>
   

3. Switch to WYSIWYG mode, so the HTML gets parsed.
   

After following these steps, the browser tab should hang.

CKEditor version: 3.4.1
Browser: Google Chrome 6.0.472.62 (Build oficial 59676)
OS: Ms Windows 7

I debugged the problem and found out that the problem is in this regular expression that is used to parse the HTML:

htmlPartsRegex:new RegExp("<(?:(?:\\/([^>]+)>)|(?:!--([\\S|\\s]*?)-->)|(?:([^\\s>]+)\\s*((?:(?:[^\"'>]+)|(?:\"[^\"]*\")|(?:'[^']*'))*)\\/?>))",'g')

Thanks in advance.

Works fine with Safari.

Couldn't reproduce it in latest Chrome.
