<p>I uploaded a GPX trace to OSM. Present at <a href="http://www.openstreetmap.org/user/mcld/traces/2402245">http://www.openstreetmap.org/user/mcld/traces/2402245</a> . I click on "Edit this trace" because I want to change the visibility setting. This takes me to <a href="http://www.openstreetmap.org/trace/2402245/edit">http://www.openstreetmap.org/trace/2402245/edit</a> as expected. I change the visibility dropdown, I press "Save changes" - this seems to take me simply to the trace's .../edit page again, and no change in the GPX metadata has occurred. (Similarly if I alter the description.)</p>
<p>(I'm using firefox 53.0 on ubuntu 16.04)</p>
<p>When I submit the form, it submits to .../edit and the post content is</p>
<pre>utf8=✓

<p>(...although I've mangled the authenticity token in case it's sensitive.) The reply to the POST is simply 200 OK.</p>
