[X] I have searched for existing issues that already report this problem, without success.
Ionic Framework Version
v8.x
Current Behavior
Since v8.2.4 Ionic components like ion-button and ion-chip produce an elm.attachShadow is not a function TypeError in Angular apps with server side rendering (SSR) enabled.
The TypeError did not occur in version 8.2.2 and prior, but in every version since 8.2.4.
Expected Behavior
No TypeError like in v8.2.2 and prior.
Steps to Reproduce
See the code reproduction URL for a minimal app on GitHub showcasing the error (steps to run the app in the README).
The modules-based Angular app was generated with Angular CLI version 18.1.3 with the command:
ng new ionic-angular-ssr-attachShadow-typeError --ssr=true --standalone=false --style=scss
I then added @ionic/angular and @ionic/angular-server, configured Ionic and switched to Angular’s older browser builder which I’m using in my actual project (and as far as I know Ionic doesn’t work in Angular standalone SSR apps using the new Vite-based application builder). See the commit history in the code reproduction repository for a detailed account of the code changes.
Once you have the code reproduction app running you will get the TypeError in the terminal.
