By some fluke, I discovered an issue with RadEditor when certain HTML is entered into the editor. This only came to my attention when one of the users of our web app notified me of browsers crashing when trying to load the content into the editor. After investigating, I created a reproducible sample than breaks the editor on Telerik's demo page, as well as the editor in my own app.
here is the offending html: careful
> Some content "really long text here; some more stuff here
Enter this html into the HTML view of the rad editor here:
Careful tho, this will probably crash your browser.
I suspect the issue is caused by whatever parser is trying to interpret that html, and it chokes on it. The real offender is the quote before 'really'. If i remove that, it seems to not be an issue. In the meantime, i removed the quote from the content so my user could edit the content. But I figured I would post the problem here so it can be fixed for future releases.
