Re: [PATCH v3 0/7] MR8251: mshtml: getAttributeNode and removal fixes.

This patch could use a split. For example:
1. Introduce the infrastructure and use it for `IHTMLElement*` interface
2. Use it for other interfaces
3. Add tests
> mshtml: Don't include non-specified attributes in getAttributeNode from IHTMLElement6.

It's not yet clear how `IHTMLElement6` will look like once we have support for IE9+ attribute. Let's skip that and later commits until it's settled, I can't review it without more context.
