bug(cdkDrag): Can't reorder edge items with different size and boundary

### 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

I'm implementing draggable horizontal list, each item may has different width (depending on content). In case if first item is shorter than second and I want swop them and I capture second item closer to right edge it's impossible to set second item as first.
Note: cdkDrag constrained by X axis and has boundary
`cdkDragLockAxis="x" [cdkDragBoundary]="dropContainer"`

### Reproduction

StackBlitz link: https://stackblitz.com/edit/roitsa?file=src%2Fexample%2Fcdk-drag-drop-horizontal-sorting-example.ts
Steps to reproduce:
1. Capture "Bronze age" closer to right side (red area in the example)
2. Try to make it first in the list (swop with "Iron")

I was trying to make workaround with `cdkDragConstrainPosition` but without success as with this function behaviour changes, item reorders immediately if I drag left. Seems weird or I do something wrong
Example with `cdkDragConstrainPosition` : https://stackblitz.com/edit/roitsa-6kbo4x?file=src%2Fexample%2Fcdk-drag-drop-horizontal-sorting-example.html

### Expected Behavior

Ability to reorder edge items constrained by cdkDragBoundary

### Actual Behavior

Can't reorder edge items

### Environment

- Angular: v16
- CDK/Material:
- Browser(s): Chrome
- Operating System (e.g. Windows, macOS, Ubuntu): macOS

リンクされている StackBlitz の再現例、特に cdk-drag-drop-horizontal-sorting-example.ts とその HTML から始め、cdkDragLockAxis="x" と cdkDragBoundary を使った横方向リストのケースを再現します。端のアイテムの幅が異なる場合に、境界によって制約されたドラッグが並べ替えにどのような影響を与えるかを追跡します。完了条件は、どちらのキャプチャ位置からでも Bronze age アイテムを Iron の前に並べ替えられることです。
