Another issue regarding recent changes to 184.108.40.206 "The rules for
parsing tokens in foreign content".
When a HTML start tag is seen (specifically "b", "big", "blockquote",
"body", "br", "center", "code", ...) the following procedure is given to
recover from the parse error:
If the stack of open elements does not have an element in scope that is
a MathML text integration point, an HTML integration point, or an
element in the HTML namespace, or if the stack of open elements has only
one element, then process the token using the rules for the "in body"
insertion mode. (fragment case)
Since the stack of open elements always has <html> at the top of the
stack, the "element in scope" algorithm will always find it, and as a
result, the first part of the condition will always fail.
This seems unintentional, and depends upon the exact way in which the
"element in scope" algorithm is defined.
Perhaps rewriting this paragraph without reference to the "element in
scope" algorithm would make the intent clearer? For example:
If the stack of open elements does not any elements that are MathML text
integration points, or HTML integration points, or that are in the HTML
namespace, or if the stack of open elements has only one element ...
