Error when trying to open Shared network tab

I'm getting this error in the web browser console:

ERROR TypeError: t.tabSubject is undefined
    tabIndex shared-networks-page.component.ts:367
    openTabBySharedNetworkId shared-networks-page.component.ts:367
    ngOnInit shared-networks-page.component.ts:184
    RxJS 10
    Angular 6
    RxJS 107

Steps to reproduce:

1. Go to the shared networks page
2. Click New shared network button
3. Go to Shared Networks tab index=0
4. Try to open any existing Shared network tab - nothing happens, error in the console appears
