Which area/package is the issue in?
vitest-angular
Description
If using nx with vitest-analog or a plain Angular project with @analogjs/vitest-angular, in both cases the error NG0304 occurs for search.
If using the default Angular Vitest integration the error does not occur.
Please provide the exception or error you saw

This is a bug with

The support for the search element was added some time ago already to the angular compiler: angular/angular#54944
It works fine on angular side. It compiles fine while building and also works with the their vitest integration.
The error only occurs on Tests with vitest Analog in a nx workspace or on a Angular project with
@analogjs/vitest-angular.I'm unsure where the error is originated
