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.

必須の Expo Snack 再現コードから始め、aspectRatio、maxWidth、flex ベースのサイズ計算、および Android での明示的な width に関して報告されたケースを検証します。これらの制約を担うランタイムのレイアウト計算を追跡します。完了条件は、maxWidth で上限を設定された width によって、要求されたアスペクト比を維持する height が生成され、再現コードのケースに対するリグレッションテストのカバレッジがあることです。
