[BUG] List & other tag behavior different between String and Element

[Skylled]

Describe the bug:

The same HTML code produces different results depending on whether I use Html.fromElement or Html.

There are quite a few discrepancies, but the most easily described is that <ol> tags no longer increment correctly. When using Html.fromElement, all list items are prepended with "0." Using the same HTML code (obtained via element.outerHtml) but with the Html() constructor, lists appear correctly.

HTML to reproduce the issue:

<ol>
<li>Item 1</li>
<li>Item 2</li>
</ol>

Expected behavior: An ordered list should enumerate correctly regardless of whether the HTML was pre-parsed.
