Current Behavior

When using custom events example InfiniteScrollCustomEvent, I will get an error on my IDE as shown below. Please note this happens when I use any custom events such as the refresher custom event etc

Expected Behavior

When using a custom event, the IDE should not show the error

Steps to Reproduce

1. Create a fresh Ionic Angular project
2. Enter the following code

In .html

<ion-infinite-scroll threshold="100px" (ionInfinite)="loadMore($event)">
          <ion-infinite-scroll-content loadingSpinner="dots" loadingText="Loading More Cosmetics...">
          </ion-infinite-scroll-content>
        </ion-infinite-scroll>

In .ts

loadMore(ev: InfiniteScrollCustomEvent) {
    this.currentPage.next(this.currentPage.value + 1);

    if (this.currentPage.value === this.maximumPages) {
      ev.target.disabled = true;
    }
  }
