Bug 160634 – Align Range.createContextualFragment() input validation with the specification

• Component: DOM
• Status: RESOLVED FIXED

[Chris Dumez]

Align Range.createContextualFragment() input validation with the specification:
- https://w3c.github.io/DOM-Parsing/#dom-element-insertadjacenthtml (Step 2)

In particular, we were throwing a NOT_SUPPORTED_ERR when element had localname "html" but was not in the HTML namespace. We should not throw in this case.

Firefox complies with the specification here.

Could move the function ieForbidsInsertHTML to Element from HTMLElement to get rid of this casting.

Could also give it a different name since there is probably some nomenclature in the standard now rather than referring to IE.

Sounds good. I'll move it to Element. However, I have trouble finding the equivalent in the specification. I suspect it may not be standard behavior.

The spec is:
- https://w3c.github.io/DOM-Parsing/#idl-def-range-createcontextualfragment(domstring)
which points to:
- https://html.spec.whatwg.org/#html-fragment-parsing-algorithm
