Issue with Dropdown menus in Firefox on a PC

[dtlyme]

Hi - we are having issues on a PC with Firefox that the dropdown menus do not work on the page builder storefront:

I don't have any issues on my Mac with Safari or Chrome. See attached photo of the issue on PC with Firefox.

It looks like the hero component and the navigation bar both have a z-index of 1.

An easy fix for this would be the change the z-index on .navigation-bar from 1 to 2 (or remove it altogether)

.navigation-bar {
border: solid #dedede;
border-top-width: medium;
border-right-width: medium;
border-bottom-width: medium;
border-left-width: medium;
border-width: 1px 0;
box-shadow: 0 2px 4px -2px rgba(0,0,0,.2);
position: relative;
text-align: center;
z-index: 2;
}
