bug(Drag and Drop): autoscroll fails in full size web view

### Is this a regression?

- [ ] Yes, this behavior used to work in the previous version

### The previous version in which this bug was not present was

_No response_

### Description

When a hybrid mobile app (Ionic Capacitor) is made with a long list of draggable items, the autoscroll fails to engage. Take the same codebase and run it on a mobile browser, it fails. Run it on a desktop browser and it works.
Notice on a desktop browser that autoscrolling only begins when the cursor is outside the html page. It is not possible to get outside the page on a full screen mobile web view since touching outside that area is touching off the screen.

### Reproduction

Steps to reproduce:
1. Build a simple Ionic Capacitor mobile app with a list
2. Add CDK Drag and Drop elements to the list
3. Run it on a phone or phone browser.
4. Drag an item form the top to near the bottom.

### Expected Behavior

List should autoscroll up when touching near edge of phone.

### Actual Behavior

List fails to autoscroll.

### Environment

- Angular: 15.2.8
- CDK/Material: 15.2.9
- Browser(s): Safari, Safari Mobile
- Operating System (e.g. Windows, macOS, Ubuntu): macOS 12.6.6
- Ionic: 5.4.16
- Capacitor 5.0.3

説明されている Ionic Capacitor セットアップおよび Safari Mobile で Angular CDK Drag and Drop の動作を再現し、デスクトップブラウザーでの動作と比較します。携帯電話の viewport の端付近でドラッグしている間の autoscroll の動作を調査します。ドラッグ中の要素がその端に到達したときに長いリストが autoscroll すれば完了です。
