[ed4becky]

Bug description: Attached is a Stackblitz that demonstrates that Typeahead throws an ExpressionChangedAfterItHasBeenCheckedError error for an Application running as zoneless (using provideExperimentalZonelessChangeDetection() )

Plunker/StackBlitz that reproduces the issue: (https://stackblitz.com/edit/stackblitz-starters-8fof6biv?file=src%2Fapp.config.ts)

Versions of ngx-bootstrap, Angular, and Bootstrap:

ngx-bootstrap: 19.0.2

Angular: 19.0.6

Bootstrap: 5.3.3

Expected behavior

Typeahead should run without generating an ExpressionChangedAfterItHasBeenCheckedError error.

I confirm that I have the same issue with angular 20.0.3 with provideZonelessChangeDetection()

Ngx-bootstrap doesn't support zoneless, as of now.
