Since nobody raised any problems with this, I've now done this.
For background, this solves this case:
Before this fix, the output is "456 123", with the "123" covered by <s>,
<u>, <tt>, and <b>, and the "123" covered by <b> and <i>. After the fix,
the output is "123 456", with the "123" covered by <s>, <u>, and <b>, and
the "456" covered by no formatting elements.
I could see an argument for leaving the elements in the list of formatting
elements (so the output would be "123 456", with the "123" covered by <s>,
<u>, and <b>, and the "456" covered by nothing, but with an <i> being
reintroduced if you ended the whole thing with "<div>789"). Let me know if
you think that's better.
This being a change to the parser, it's risky; in fact it could change the
styles of nodes. However, I think getting the output of the parser to be
in the same order as the input is something that is far more important
than getting the exact formatting styles correct. This is not just moving
nodes out of a <table>; the old parser rules here moved nodes way off into
earlier parts of the DOM with no intuitive logic.
