component store 14.0.1 typing issue

my.store.ts

interface SomeType {
  name: string;
  prop: string;
}

export abstract class MyStore<
  QueryVariables extends SomeType
> extends ComponentStore<any> {
  protected abstract readonly query$: Observable<Omit<QueryVariables, 'name'>>;

  readonly load = this.effect(
    (origin$: Observable<Omit<QueryVariables, 'name'> | null>) => origin$
  );

  protected constructor() {
    super();
  }

  protected initializeLoad() {
    this.load(this.query$);
  }
}

Where as this works:

import { ComponentStore } from '@ngrx/component-store';
import { Observable } from 'rxjs';

interface SomeType {
  name: string;
  prop: string;
}

export abstract class MyStore<
  QueryVariables extends SomeType
> extends ComponentStore<any> {
  protected abstract readonly query$: Observable<Omit<SomeType, 'name'>>;

  readonly load = this.effect(
    (origin$: Observable<Omit<SomeType, 'name'> | null>) => origin$
  );

  protected constructor() {
    super();
  }

  protected initializeLoad() {
    this.load(this.query$);
  }
}

If I use the type directly instead of the generic to type the observable it passes type checking totally fine.
