Error: $sanitize:elclob

Failed to sanitize html because the element is clobbered

This error occurs when $sanitize sanitizer is unable to traverse the HTML because one or more of the elements in the HTML have been "clobbered". This could be a sign that the payload contains code attempting to cause a DoS attack on the browser.

Typically clobbering breaks the nextSibling property on an element so that it points to one of its child nodes. This makes it impossible to walk the HTML tree without getting stuck in an infinite loop, which causes the browser to freeze.
