Descripción
### 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
Guía de contribución
Línea de trabajo
Comienza con las reproducciones de StackBlitz enlazadas, especialmente cdk-drag-drop-horizontal-sorting-example.ts y su HTML, y reproduce el caso de una lista horizontal con cdkDragLockAxis="x" y cdkDragBoundary. Traza cómo el arrastre restringido por los límites afecta a la ordenación cuando los elementos de los extremos tienen anchos diferentes; el trabajo estará terminado cuando el elemento Bronze age pueda reordenarse delante de Iron desde cualquiera de las dos posiciones iniciales.
