wp:post-date format including html tag

[jasonmader]

<!-- wp:post-date {"format":"d <span>M</span>"} -->

results in,

<time datetime="2024-05-04T11:38:30-04:00">
    04 <30pam5>May</30pam5>
</time>

escaping \s and \n, which seems like it should work, only results in,

<time datetime="2024-05-04T11:38:30-04:00">May 4, 2024</time>

alas, this does work,

<?php
{"format":"d <\\s\\p\\a\\n>M</\\s\\p\\a\\n>"}
