React-Bootstrap Modal focus trap and third-party focus management

Modal Focus Management

The React-Bootstrap Modal component implements a focus trap to ensure keyboard navigation remains within the dialog boundaries while the modal is active. This behavior is essential for accessibility and ensures that screen reader users do not accidentally navigate to the background page content.

In complex application architectures, other libraries or custom hooks may attempt to manage global focus or trigger focus shifts based on external state changes. When these third-party focus managers operate simultaneously with the Modal's internal logic, it creates uncertainty regarding which system maintains priority over the active element.

• Constraint: The Modal must maintain accessibility standards by trapping focus.
• Conflict: External focus management logic may attempt to move focus outside the Modal DOM tree.

How does the Modal component resolve focus priority when a third-party library attempts to shift focus away from the dialog? Is there a configuration to disable the internal focus trap without breaking the aria-modal accessibility contract?
