Interactive Grid inline edit focus trap still inconsistent after validation error in APEX 21.1+

Background

Since APEX 21.1 the Interactive Grid gained keyboard navigation for its toolbar and column headers, yet the inline edit mode continues to trap focus inconsistently when a validation error occurs. The behavior differs between Chrome 118+ and Firefox 119+ because each browser implements ARIA modal focus handling differently.

Constraints

• Must retain WCAG 2.1 AA compliance for screen‑reader users.
• Solution must work across all supported browsers without requiring a custom theme.
• Declarative configuration is preferred; custom JavaScript should be a last resort.

Open Questions

1. Has any APEX 23.x release introduced a declarative attribute to control focus restoration after a validation error?
2. What is the recommended pattern for managing focus in inline edit mode that preserves screen‑reader announcements across Chrome and Firefox?
3. Are there documented workarounds that keep the inline edit UX intact while eliminating the focus trap?
