Changelog Entry

• (Experimental) Added botframework-webchat-fluent-theme package for applying Fluent UI theme to Web Chat, by @compulim and @OEvgeny
  • Added keyboard navigation support into suggested actions, by @OEvgeny in PR #5154

Description

Implemented roving focus using existing implementation as a reference. The new component is now used for suggested actions keyboard support.

Design

The new rovingFocus module implements the roving focus exposing only the RovingFocusProvider and useRovingFocusItemRef.

The module is private for suggestedActions for now. When we find other use-case, we can reconsider and refactor it.

Specific Changes

• Implemented the roving focus functionality for fluent theme package
• Added roving focus into suggested actions
