<pre>Yes, rewriting a POST request on a 302 redirect is correct behavior, and per the comment in the Chromium bug that you quoted, Chromium does the same.
Given that you have a case where Safari behaves differently than Chrome, there has to be some other subtlety in your case.
We do have a report about incorrectly rewriting non-POST requests, tracked as <a class="bz_bug_link
bz_status_UNCONFIRMED "
title="UNCONFIRMED - XHR rewrites non-POST methods upon 301/302 redirects"
href="show_bug.cgi?id=46183">bug 46183</a>. But since yours is a POST, that is not what is happening here.</pre>
