When sub menu is added then parent of submenu is not visible.

After Fixing the issue

I have applied the MR9 patch [It applied cleanly], but with and without the patch the issue looks the same, no visual changes are displayed. The Issue is not being reproduced. Attaching SS for the same.

@alok_singh Sub menus are not allowed by the GOV.UK design System. In fact menus in the header are very much discouraged see the Service navigation component which is implimented in the the new V2.1.x release.

I'm closing this ticket as it is outside the scope of this theme.
