This was added by commit 7f174213ed, and
appears to have been designed for responses that are *successful* but
falsy. Logically, these should not implicitly represent a failure to
be retried if it were.
Note from tabbott: The background is that this idempotent retry loop
was a hacky workaround for a bug we never understood but saw daily in
production. Especially during server restarts / client reloads,
something would result in 200 responses with no data being seen by the
frontend, despite the Django server not having received/processed the
request. Fortunately, this strange failure mode appears to have
stopped happening in late 2019, so we can delete this hack.

We attach the DOM for the modal to the body element
to avoid style interference from other elements and having to choose
a separate parent element for every single dialog_widget.
We used html_submit_button to pass text to be present in the modal
submit button. There are only two possible options as of now -
"Confirm" and "Save changes" and the correct one can be determined
using is_confirm_modal parameter. So, we remove this paramter for
now and we can add it later if we have more type of modals using
this widget.
