Collapsed content becomes inert. Regression tests verify focus order, inert behavior, and accessibility compliance. ChangesCard list accessibility
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to When an unlabeled CardList is collapsed while its content is focused, that content becomes unavailable without a predictable replacement focus target, which can disrupt keyboard navigation. The change is otherwise localized and mergeable with explicit owner awareness or follow-up. Sequence Diagram(s)sequenceDiagram

- Line 464: Add a consumer-facing changeset for the packages/core package
describing the ix-card-list accessibility behavior change caused by applying
inert during collapse; do not alter the implementation, and only omit the
changeset if the change is explicitly established as internal-only.
- Around line 188-190: Ensure the collapsed-state focus flow in the CardList
component always has a valid focus destination when label is absent, rather than
relying on the optional collapseButton. Either render a stable focusable target
for unlabeled collapsible lists or require and document label before enabling
collapse, and add regression coverage for the unlabeled configuration.
- Around line 193-196: Update hasFocusWithinListContent to check :focus-within
on the CardList__Content container rather than only the elements returned by
getListChildren(), so the internal show-more card is included. Add a regression
test that focuses the show-more card before setting collapse to true.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Provide a focus destination when label is absent.
label is optional, but CardListTitle returns null without it. In that configuration, collapseButton is undefined. The optional call does nothing, and Line 464 then makes the focused content inert.
Render a stable focus target for collapsible lists without a label, or enforce and document a label requirement before allowing collapse. Add regression coverage for this configuration.

Add a consumer-facing changeset.
This changes the public accessibility behavior of ix-card-list. No changeset is included in this cohort. Add a changeset for packages/core, or explicitly justify why this behavior change is internal-only.
As per coding guidelines, "Update tests, documentation, examples, and changesets when user-facing behavior, APIs, styling, accessibility, or package output changes." As per path instructions, "Changesets are required for public API updates, behavior changes, styling/theming changes, accessibility changes, and bug fixes with user impact."
