Current behavior

<div>
  <a [routerLink]="['emails']">Emails</a>
  <a [routerLink]="['contacts']">Contacts</a>
  <a [routerLink]="[{outlets: {aux: ['auxiliary']}}]">Open an auxiliary route</a>
</div>

<router-outlet></router-outlet>
<router-outlet name="aux"></router-outlet>

So far, it’s nearly fine.

• /emails is diplaying fine
• /contacts is diplaying fine
• /emails(aux:auxiliary) is diplaying fine at loading
• /contacts(aux:auxiliary) is diplaying fine at loading

When the auxiliary is in URL, it’s ok the first time we reach it.
But then, if I click on <a [routerLink]="['emails']">Emails</a>, my aux outlet is not displayed anymore even tho the URL is still http://localhost:4200/emails(aux:auxiliary).

So my question is, how can we change the primary URL, without changing auxiliary routes ? (if no auxiliary, just go to new URL, if auxiliary, go to URL + auxiliary).

I tried :

<a [routerLink]="['emails', {outlets: {aux: ['/']}}]">Emails</a>
<a [routerLink]="['contacts', {outlets: {aux: ['/']}}]">Contacts</a>

and also

<a [routerLink]="['emails', {outlets: {aux: ['./']}}]">Emails</a>
<a [routerLink]="['contacts', {outlets: {aux: ['./']}}]">Contacts</a>

But it’s not working either.

Expected behavior

Stay on current primary route without changing auxiliary.
