<p dir="auto">I'd assume that changing the ordering would fix this but as this change appears to have been made after RC1, it could well break something else.</p>

<p dir="auto">the problem happens on mobile, tablet in ios everything is working, but using firefox on a tablet with android by clicking the submenu instead of open it all closes, the bug was partly solved in version 2.3.1 before or since in ios worked, now working in firefox was missing and perhaps other browser used in tablets.</p>
