Element  $element,

)

Insert or reparent an element.

Create p-wrappers or split the tag stack as necessary.

Consider the following insertion locations. The parent may be:

  • A: A body or blockquote (!!needsPWrapping)
  • B: A p-wrapper (!!isPWrapper)
  • C: A descendant of a p-wrapper (!!ancestorPNode)
    • CS: With splittable formatting elements in the stack region up to the p-wrapper
    • CU: With one or more unsplittable elements in the stack region up to the p-wrapper
  • D: Not a descendant of a p-wrapper (!ancestorNode)
    • DS: With splittable formatting elements in the stack region up to the body or blockquote
    • DU: With one or more unsplittable elements in the stack region up to the body or blockquote

And consider that we may insert two types of element:

  • b: block
  • i: inline

We handle the insertion as follows:

  • A/i: Create a p-wrapper, insert under it
  • A/b: Insert as normal
  • B/i: Insert as normal
  • B/b: Close the p-wrapper, insert under the body/blockquote (wrap base) instead)
  • C/i: Insert as normal
  • CS/b: Split the tag stack, insert the block under cloned formatting elements which have the wrap base (the parent of the p-wrap) as their ultimate parent.
  • CU/b: Disable the p-wrap, by reparenting the currently open child of the p-wrap under the p-wrap's parent. Then insert the block as normal.
  • D/b: Insert as normal
  • DS/i: Split the tag stack, creating a new p-wrapper as the ultimate parent of the formatting elements thus cloned. The parent of the p-wrapper is the body or blockquote.
  • DU/i: Insert as normal

FIXME: fostering ($preposition == BEFORE) is mostly done by inserting as normal, the full algorithm is not followed.

For the purposes of this class, "metadata" elements are those that should neither trigger p-wrapping nor stop an outer p-wrapping, typically those that are themselves invisible in a browser's rendering.

This isn't a complete list, it's just the tags that we're likely to encounter in practice.
