Summary
Fixes #4511.
When an unrecognized element is encountered, it is replaced with its children. This process wasn't accounted for when looping over the children of an element to sanitize. This PR ensures that when a child element is removed, the next loop iteration will pick up with the first valid descendant node that was in the now-removed child.
