<p>I'm wondering if this is related to <a href="https://github.com/openstreetmap/openstreetmap-website/issues/567" class="issue-link" title="Going back from a changeset to the history needs two clicks">#567</a> and was fixed in <a href="https://github.com/openstreetmap/openstreetmap-website/commit/9e25f5563d87fd6bce5b1679790d6d9c9e34e875" class="commit-link"><tt>9e25f55</tt></a>. It's hard to be sure, but I'll keep my eyes open as I use changeset lists a <em>lot</em>.</p>
