Now, it doesn't have </table> stripped,
or the closing </td>.

As Weston suggested,
to prevent regressions.

Weston mentioned that this could have
single or no quotes.
I hadn't thought of that.

Allow spaces in the closing </script>,
like </script >
Also, make this case-insensitive
and ensure the quotes types are the same.

The conflicts were deleted files:
src/Dom/Document.php
tests/php/test-class-amp-dom-document.php

This simply moves the changes in those
files to the relevant new files.

Also, correct a function name
in a DocBlock tag.

Maybe <script async shouldn't be changed to
<script async=""
But with how the workaround works,
it sets the script attributes to their previous attributes.
So <script async
will eventually end up as <script async="".
