Hiding table rows works, but fading out does not

I was hoping to add a fade animation when hiding table rows.

This works:

$('#myTable > tbody > tr').not("[name*=" + thing + "]").hide()

This does not:

$('#myTable > tbody > tr').not("[name*=" + thing + "]").fadeOut("slow")

I’m using the full, uncompressed (non-slim version, I believe, of jQuery):

<script
  src="https://code.jquery.com/jquery-3.5.1.js"
  integrity="sha256-QWo7LDvxbWT2tbbQ97B53yJnYU3WhH/C8ycbRAkjPDc="
  crossorigin="anonymous"></script>

$("tr:hidden", "#mytable")...
