SuperHTML complains about span > del and span > ins #127
Description
SuperHTML Version
0.6.2
Steps to Reproduce and Observed Behavior
Here's the HTML:
<!DOCTYPE html>
<html lang='en-US'>
<head>
<meta charset='UTF-8'>
<title>span > del and span > ins complaints</title>
</head>
<body>
<h1>
<code>span > del</code>
and <code>span > ins</code>
complaints
</h1>
<p>I think <span><del>-</del><ins>+</ins>[NSString alloc]</span>
is a fine method name.</p>
</body>
</html>superhtml doesn't like the del and ins where they are:
> superhtml check index.html
index.html:12:20: invalid nesting under <span>
<p>I think <span><del>-</del><ins>+</ins>[NSString alloc]</span>
^^^
index.html:12:32: invalid nesting under <span>
<p>I think <span><del>-</del><ins>+</ins>[NSString alloc]</span>
^^^
Expected Output according to the HTML spec
I expect superhtml to not complain about this.
https://html.spec.whatwg.org/multipage/edits.html#the-del-element says that del can be used where phrasing content is expected.
Phrasing content has a long list of tags that count as phrasing content, and span is in the list.
Same thing for ins.
I don't think I'm misreading the spec.
