i have a Angular 19 SSR Website with provideClientHydration(). If i Activate this feature, i get NG0507 error. But i'm not able to figure out whats going wrong.
If i watch the Website with Inspector i extract the HTML to BeyondCompare. And i use "Show page source text" ("Seitenquelltext anzeigen") in browser to compare the both HTML.
And i see some differences, but i dont know how i can handle it.
It looks like, that all selectors in Browser ends with ="" and all selectors in Server doesnt do it.
Example: Browser:
<app-navigation _nghost-app-webabo-c3616982104="" ng-reflect-horizontal-navigation="true" ngh="1">
Server:
<app-navigation _nghost-app-webabo-c3616982104 ng-reflect-horizontal-navigation="true" ngh="1">
I have found a second difference: Browser:

Other differences i cannot see. Is it possible that this is the reason for my error? If yes, how can i fix it? I'm running in dev mode.
