Redirects on local anchor reference

[cascesme]

I have defined a fallback route for ui-router to use when it cannot identify the route the user is trying to access, using the otherwise param:

@NgModule({
    imports: [
        UIRouterModule.forRoot({ states, useHash: true, otherwise: '/', config: routerConfigFn }),

Using angular 10 with ui-router 8.0.1 with this html:

<a href="#id1">link</a>
.....
<div id="id1">...</div>

Actual:

When I click the link ui-router identifies the route as not recognized and enters the fallback. The result will be the fallback page in this case the '/' root. I cannot remove this otherwise because I need it for other cases.

Expected

UI-Router should ignore this route, and scroll down to the anchor.

Solutions I've tried

Adding a target to self in the <a> element like so:

<a href="#id1" target="_self">Link</a>

But it didn't change anything. I appreciate your help.
