aspectRatio ignores maxWidth constraint in dimension calculations

Description

When a View has both aspectRatio and maxWidth style properties, the aspect ratio calculation ignores the maxWidth constraint.

While maxWidth is correctly applied to limit the view's final width, aspectRatio appears to compute dimensions based only on explicit or implicit width values, not on the effective constrained width.

Steps to reproduce

1. Create a View with aspectRatio: 3 and either:

• No explicit width (flex-based sizing), or
• Explicit width (e.g., width: 300)
• Add maxWidth: 200 (smaller than effective width) to the same View

2. Observe the aspect ratio is distorted:

• Width correctly capped at 200px
• Height still calculated from original width (300px)
• Resulting ratio ≠ 3

See repro for full example.

Screenshots and Videos

Observe how aspectRatio always fails when applying a maxWidth, both on iOS and Android.

Commencez par le reproducteur Expo Snack obligatoire et vérifiez les cas signalés impliquant aspectRatio, maxWidth, le dimensionnement basé sur flex et une largeur explicite sur Android. Suivez le calcul de layout à l’exécution responsable de ces contraintes ; le travail est terminé lorsqu’une largeur plafonnée par maxWidth produit une hauteur qui préserve le ratio d’aspect demandé, avec une couverture de régression pour les cas du reproducteur.
