Sidenav not auto-expanding based on routerlink

*Expected behavior*Sidenav menu should expand automatically on matched routerlink

*Actual behavior*Menu is not expanding. However, when menu is clicked you can see that the menu-item indeed has the active class set, simply just not visible.

<mdb-sidenav-item>
<a class="sidenav-link"><i class="fas fa-cubes fa-fw fa-lg me-3"></i>Accounts</a>
<ul class="sidenav-collapse" mdbCollapse>
    <li class="sidenav-item"><a class="sidenav-link" [routerLink]="['/accounts/request']" routerLinkActive="active" [routerLinkActiveOptions]="{exact: true}" mdbWavesEffect><i class="fa fa-cube me-1"></i>Request account</a></li>
    <li class="sidenav-item"><a class="sidenav-link" [routerLink]="['/accounts']" routerLinkActive="active" [routerLinkActiveOptions]="{exact: true}" mdbWavesEffect><i class="fa fa-cog me-1"></i>Manage accounts</a></li>
</ul>
<mdb-sidenav-item>

I'm on v5 beta 8 at the moment, as I could see in the changelog that there was a fix in this particular area. Coud you please share an example on how this is supposed to work, as there is no such thing in the Sidenav documentation?
