Hovering Help in toolbar menu expand the Store settings submenu

Hello (again),

I create a new issue about the menu as it's another problem.

When I hover the Help link in the toolbar menu, it expand the Store settings submenu.

When I look the HTML source, it appears that the Store settings and Help menu are under the same group. See the code :

<ul class="menu group group-5"><li class="first expanded"><a href="/en/admin/commerce/config">Store settings</a><div class="toolbar-menu-wrapper"><ul class="menu group group-0"><li class="first last expanded"><a href="/en/admin/commerce/config/advanced-settings">Advanced store settings</a><div class="toolbar-menu-wrapper"><ul class="menu group group-0"><li class="first collapsed"><a title="Manage customer profiles and profile types in the store." href="/en/admin/commerce/customer-profiles">Customer profiles</a></li>
<li class="leaf"><a title="See all the available services for your Commerce Kickstart" href="/en/admin/modules/service-providers">Service providers</a></li>
<li class="leaf"><a title="Manage shipping methods and services." href="/en/admin/commerce/config/shipping">Shipping</a></li>
<li class="leaf"><a title="Manage tax rates and types." href="/en/admin/commerce/config/taxes">Taxes</a></li>
<li class="collapsed"><a title="Enable and configure payment method rule configurations." href="/en/admin/commerce/config/payment-methods">Payment methods</a></li>
<li class="leaf"><a title="Customize the checkout form and configure checkout rules." href="/en/admin/commerce/config/checkout">Checkout settings</a></li>
<li class="leaf"><a title="Configure the default currency and display settings." href="/en/admin/commerce/config/currency">Currency settings</a></li>
<li class="collapsed"><a title="Manage line item types for your store." href="/en/admin/commerce/config/line-items">Line item types</a></li>
<li class="leaf"><a title="Configure general order settings, fields, and displays." href="/en/admin/commerce/config/order">Order settings</a></li>
<li class="leaf"><a title="Enable and configure product pricing rules and pre-calculation." href="/en/admin/commerce/config/product-pricing">Pricing rules</a></li>
<li class="last leaf"><a title="todo." href="/en/admin/commerce/config/demo">Reset</a></li>
</ul></div></li>
</ul><ul class="menu group group-1"><li class="first last expanded"><a href="/en/admin/commerce/config/product-settings">Product settings</a><div class="toolbar-menu-wrapper"><ul class="menu group group-0"><li class="first leaf"><a title="Manage tagging, categorization, and classification of your products." href="/en/admin/commerce/config/products-categories">Categories</a></li>
<li class="last leaf"><a title="Manage products types for your store." href="/en/admin/commerce/config/types">Product types</a></li>
</ul></div></li>
</ul><ul class="menu group group-2"><li class="first last expanded"><a href="/en/admin/commerce/config/promotions">Promotions</a><div class="toolbar-menu-wrapper"><ul class="menu group group-0"><li class="first last collapsed"><a title="Manage discounts." href="/en/admin/commerce/store/discounts">Discounts</a></li>
</ul></div></li>
</ul></div></li>
<li class="last expanded"><a title="Find all the help you need to start using your store." href="/en/admin/help">Help</a><div class="toolbar-menu-wrapper"><ul class="menu group group-0"><li class="first last leaf"><span class="nolink">Development</span></li>
</ul></div></li>
</ul>

I got that problem with a fresh install. And even if I changed the order of some menu items, I didn't change the Help one (as you can see in the attached screenshot, I don't have a reset link for that menu item which prove I didn't touch it).

Regards,

Alex
