Description of problem:
It's not possible to hover over sub menu for chosen item in main menu. The sub-menu closes.

Version-Release number of selected component (if applicable):
rhscon-core-0.0.24-1.el7scon.x86_64
rhscon-ui-0.0.39-1.el7scon.noarch
rhscon-ceph-0.0.23-1.el7scon.x86_64

How reproducible:
100%

Steps to Reproduce:
1. Click on Admin (or on Storage) item in main menu
2. Move the mouse cursor to the related sub-menu area
3.

Actual results:
Sub-menu closes after short time

Expected results:
Sub-menu should stay open until the mouse cursor is on it.

Additional info:
If the same is done for the other sub-menu, not active one, it is working properly. Sub-menu stays open till the cursor is over it. Where not active means that the related item in main menu is not highlighted e.g. clusters page are opened and so Clusters item is highlighted and both Storage and Admin sub-menus work correctly.
