/**
* Publishes to a topic using XMLHttpRequest (XHR), and returns a Promise with the active request.
* Unfortunately, fetch() does not support a progress hook, which is why XHR has to be used.
*
* Firefox XHR bug:
* Firefox has a bug(?), which returns 0 and "" for all fields of the XHR response in the case of an error,
* so we cannot determine the exact error. It also sometimes complains about CORS violations, even when the
* correct headers are clearly set. It's quite the odd behavior.
*
* There is an example, and the bug report here:
* - https://bugzilla.mozilla.org/show_bug.cgi?id=1733755
* - https://gist.github.com/binwiederhier/627f146d1959799be207ad8c17a8f345
