Hi,
we hit a bug with using 'warning' emoticon. On creating page with inly this emoticon, we get following:
<p><img class="emoticon emoticon-warning" src="/s/en_GB/7901/9eed016aaa593220cd98620fec88bcbd9fd55893/_/images/icons/emoticons/warning.svg" data-emoticon-name="warning" alt="(warning)" /></p>
and everything works as expected. If we add some text, confluence use another src for the Image (http!) an breaks https:
<p>Add some text <img class="emoticon emoticon-warning" title="(warning)" src="http://docs-test.fhe3.com/s/en_GB/7901/9eed016aaa593220cd98620fec88bcbd9fd55893/_/images/icons/emoticons/warning.svg" alt="(warning)" border="0"/></p>
This happens with all emoticons on same way.
