## 2024-05-28 - Full-screen background elements receiving focus
**Learning:** In the app's modals and drawers (`MobileMenu.tsx`, `DiscussionComposer.tsx`), full-screen backdrop overlay elements implemented with `<button>` receive keyboard focus by default, which creates invisible and confusing tab stops for users relying on keyboard navigation.
**Action:** When implementing clickable `<button>` elements that act purely as visual backdrops (e.g., for "click away to close"), ensure they include `tabIndex={-1}` to remove them from the tab order and `cursor-default` to indicate they are not standard interactive buttons.

Update the documented action to include aria-hidden="true" and the removal of aria-label to align with the recommended accessibility best practices for visual backdrops.

Since the backdrop button is removed from the sequential tab order using tabIndex={-1}, it should also be hidden from screen readers using aria-hidden="true" and its aria-label should be removed.

Keeping aria-label on a non-focusable element (tabIndex={-1}) is an accessibility anti-pattern. Screen reader users navigating via touch or virtual cursor will still encounter the backdrop as a giant interactive button, while keyboard-only users cannot focus it. Since the modal already has an explicit, accessible close button, the backdrop is redundant and should be completely hidden from assistive technologies.

Increasing the test timeout to 10 seconds to accommodate a hanging process execution is a workaround that slows down the test suite.

Instead, you should mock the underlying process execution (e.g., using vi.spyOn or mocking the execution utility/module). Unit tests should be fast, deterministic, and isolated from the host environment's permissions or process execution.
