### Ionic Framework Version

v7.x

### Current Behavior

ionic infinity scroll not working until the last card touches the end
I mean, I have an API, and fetching it pagewise, 1 page will have 10 item cards, and suppose if the screen is large, those 10 items will occupy half of the screen, so the last card won't touch the screen. It is not filling whole screen so new page won't appear

### Expected Behavior

It supposed to fetch all pages to fulfill the whole screen at a time. If fetching the API works 2 times (20 cards and the last card reaches the end), then it should work like this: Once it touches the end of the screen, then there's no issue.

### Steps to Reproduce

1. Implement an api which supports pagination (e.g. news, blogs, images)
2. Page size should be 2 or 3 (depending on screen and it should not touch the end of the screen)
3. Boom. Here's the bug: The 2nd page won't be fetched by API until you zoom the screen and let last card touch the bottom of the screen.

### Code Reproduction URL

### Ionic Info

@ionic/angular": "^7.0.0

### Additional Information

_No response_

Start with the reproduction URL and the @ionic/angular v7.x infinite-scroll behavior using the reported paginated API and small page sizes. Check why loading stops when the last card does not reach the screen bottom. Done means subsequent pages load automatically until the viewport is filled, without requiring zooming or resizing.
