Description

Code Sandbox

"Hover" button in "Interactions" example

Steps to reproduce

Tab to open hover button

Actual behavior

Unable to access menu items with keyboard navigation

Expected behavior

Should be able to tab to menu items without popover closing, or otherwise able to access menu items with keyboard navigation

Possible solution

Is the user expected to implement custom open control if accessibility is required? It would be nice to get this out of the box!

Note that CLICK interactionKind works as expected, perhaps if TAB key opens the popover it acts more like how the click action currently works.

Research direction
Investigate the Popover2 component's source code, specifically the interaction handlers for HOVER interactionKind. The goal is to ensure that when the popover is opened via hover and the user presses Tab, focus moves to the first focusable element inside the popover without closing it. Refer to the existing CLICK interactionKind implementation for a pattern. Key files likely include the Popover2 component and its interaction management logic.
