Tags with multiple not-quoted attributes are not being properly extracted.

[gushuro]

When extracting an abbreviation where a child element has multiple attributes that are not quoted, part of it is wrongly identified as an html tag. Therefore, it fails to extract the whole abbreviation.

Example:
isAtHTMLTag(new StreamReader('div[foo=bar foo2=bar2]>')) returns true.

Therefore, when trying to extract abbreviation from something like div[foo=bar foo2=bar2]>ul and then expand it we get div[foo=bar foo2=bar2]><ul></ul> instead of

<div foo="bar" foo2="bar2">
	<ul></ul>
</div>
