CxSideNav component does not properly highlight menu items provided with ngTemplateOutlet

Is this a bug, enhancement, or feature request?

Bug

Describe your proposal.

The issue is related to fdx-side-nav component. If the menu item (<li fdx-nested-list-item>) is stored in the <ng-template> and declared with <ng-container *ngTemplateOutlet="templateListItem"></ng-container>, Cx Side Nav does not count it when highlighting selected/not selected menu items

Can you handle that on the application side

Can make it better using routerLinkActive directive, but still not everything can be fixed by this "workaround" (see stackblitz section)

Which versions of Angular and Fundamental Library for Angular are affected? Please, specify the exact version. (If this is a feature request, use current version.)

Angular: 18.2
fundamental-ngx: 0.52.1

Previous versions of fundamental-ngx are also affected

(See stackblitz section)

Please provide stackblitz example(s).

https://stackblitz.com/~/github.com/alex-makarenko/fdx-side-nav-bug See app.component.html for details, Template List Item menu item is provided by ngTemplateOutlet. Steps to reproduce the bug: 1) Click on Template List Item (it gets selected) 2) Click on any other list item, e.g. (Nested List Item)

Template List Item remains selected. It is not taken into account by Cx Side Nav component when calculating selected/de-selected menu items.

https://stackblitz.com/~/github.com/alex-makarenko/fdx-side-nav-bug/tree/routerLinkActive (workaround) I use here [routerLink]="['/nested-list-item']" routerLinkActive="is-selected" to manually control selected state. Even in this example, a part of the issue still there: 1) Click on Template List Item (it gets selected) 2) Click on Nested List Item (it gets selected, previous item is deselected) 3) Click back on Template List item

Nested List group remains selected
