Laravel backpack dropdown menu issue

Question

I have created a drop down menu with some links. It works correctly on desktop but on mobile there is a strange issue. When I expand the menu, it doesn't push down the other menu below it. However if I reload the page once it does! In other words when I open a page once it doesn't push it down and when I refresh it it does. If I then try refresh it a second time then the issue is back and so on. Check the photos for the exact issue:

No issue

And here is the relevant (To my understanding) code:

<!-- This file is used to store sidebar items, starting with Backpack\Base 0.9.0 -->
<li><a href="{{ backpack_url('dashboard') }}"><i class="fa fa-dashboard"></i><span>{{ trans('backpack::base.dashboard') }}</span></a></li>
@if (Auth::user()->admin) 
<!-- @if(isset($company) && !Auth::user()->admin)
<li class="treeview active menu-open">

<li class="treeview">

    <a href="#">

    <span class="pull-right-container">

        <ul class="treeview-menu">

The issue was indeed JS related and it's an addition of backpack and not AdminLTE.

This code was causing a session variable to be saved that was "getting forgotten" on the refreshes causing problems with the theme:

/* Store sidebar state */
/*         $('.sidebar-toggle').click(function(event) {
          event.preventDefault();
          if (Boolean(sessionStorage.getItem('sidebar-toggle-collapsed'))) {
            sessionStorage.setItem('sidebar-toggle-collapsed', '');
          } else {
            sessionStorage.setItem('sidebar-toggle-collapsed', '1');
          }
        });

I commented it out and the problem is gone.

PS: This code resides in the layout.blade.php of the backpack default theme.
