Clicking "edit" for a specific revision on the mobile theme, gets one the expected revision and an edit screen with a dropdown to select another revision. Good. However, selecting another revision on that edit screen has no effect; while on the regular site the page reloads with a different URL, on mobile nothing happens.
Chrome remote debugging does not show any error. It seems that
<select id="revisions-list" name="revisions-list" tabindex="99">
...has no handler on mobile, while on the regular sites the page itself defines:
<script type="text/javascript">
$(function() {
$("#wmd-input").focus();
$("#title").focus();
$("#revisions-list").change(function() {
window.location = '/posts/140020/edit/' + $(this).val();
});
});
</script>
Tested on both the stock Android 4.1 browser, Chrome on Android 4.1, and Safari on iOS 4.3.3. Same results when using the mobile theme in a regular desktop browser.
As an aside, clicking "edit" on mobile always gets me the edit screen with the revision dropdown, even when clicking "edit" or "improve" below a post. I assume that this is by design. (It's just like when not using inline editing on the regular site, like when one has JavaScript disabled.)
