Topic: why sup is not allowed in pre

hi, thanks for such awesome project.

i used htmllawed in graby to crawl and process web pages.

recently, i found wikipedia have some page like this

<pre>algorithm is...over 2<sup>32</sup> blablabla </pre>

however, there is a momkid relation which will not allow sup in pre, so the outcome becomes

<pre>algorithm is...over 2</pre><sup>32</sup> blablabla

the pre is inserted in the wrong place.

so I tried to skim through the readme and search a little on the internet, but can not understand it.

my question is

1. the reason for invalid monkid relationship.
2. is it the intended behavior to insert pre before sup?

Re: why sup is not allowed in pre

Thank you for noting this issue. Element sup is permitted in pre and I will soon release a new version to fix the issue. Till then you can edit the htmLawed code: in function hl_bal, edit array invalidMomKidAr for key value of pre to remove sup.

In older HTML standard specification, sup was not permitted*, and htmLawed's logic is still based on that old specification.

Please report any similar nesting issue if you notice them.
