|

|
|
* The following is a protection against author incompetence--not against

* The basic idea is that when the tree builder stack gets too deep,

* append operations no longer append to the node that the HTML parsing
|
|
* algorithm says they should but instead text nodes are append to the last
|
|
* element that was seen before a magic tree builder stack threshold was
|
|
* reached and element and comment nodes aren't appended to the DOM at all.
|
|
*
|
|
* However, for security reasons, non-child descendant text nodes inside an
|
|
* SVG script or style element should not become children. Also, non-cell
|
|
* table elements shouldn't be used as surrogate parents for user experience
