AutoLinkResolver looks in the wrong scope

When turning on MarkupSettings#automaticLinking, AutoLinkResolver is supposed to touch tags like <img> and <a> and set their src/href attributes so that packaged resources are correctly referenced.

I found a situation where that does not work: If you have a panel, and e.g. an <img> tag inside that panel, and the <img> tag is NOT enclosed in a container component, it looks for the resource in the scope of the surrounding component, not in the panel's scope. It obviously can't find it there, so it just dumps the raw attribute.

If you put that <img> tag into a MarkupContainer (like WMC) then it works correctly. So it looks like the scope is off-by-one or something like that. I'll investigate.
